I is the current flowing through the series. In this combination, the resistors are connected in a parallel manner. The heating effect of the electric current explains that during the flow of electrical current, the energy source is required to keep expanding to maintain the flow of current. Some part of this energy is consumed in useful work while some part is expended in the form of heat and raises the temperature. When the source energy gets dissipated continually in the form of heat, it creates the heating effect of electric current.
During the electric current, heat gets dissipated and converts the useful electrical energy into heat. This heat is dangerous for electrical circuits if it goes beyond the acceptable limit, as it might damage the important component by raising the temperature. However, the heating effect of electric current can be useful when utilised properly.
Appliances like an electric toaster, oven, kettle, heater, iron, etc. An electrical bulb uses the electrical heat to produce the light. So, when the heat is generated during the electrical current, it absorbs the heat, gets hot and emits the light. Going through the Class 10 Electricity notes, you must remember that an electrical circuit has a fuse component that protects the circuit in case of any rapid increase in electric current. A fuse is made up of a low melting point alloys or metals like copper, iron, lead, etc.
When the electrical current increases than the specified value, the temperature increases and melts the fuse wire. Thus, it breaks the circuit and saves the appliance from any damage. The rate at which the electric energy is dissipated in an electric current is called electric power. The SI unit of electrical power is the watt W , and the unit of electric energy is watt-hour W h.
Because the unit watt is relatively small in the calculation, it is often replaced by the kilowatt. One kilowatt equals watts. Since electrical energy is a product of power and time, the commercial unit of electric energy when 1 watt of power is used for 1 hour is defined as kilowatt per hour kW h known as a unit. Now that you are familiarised with the major concepts of this chapter through our Class 10 Electricity notes, here are some important questions and solved numericals for you:.
Q: What will be the power of the bulb if connected to a V generator with the current flow of 0. Q: An electric bulb draws the electrical current of 0.

Question 7: The values of the current I flowing in a given resistor for the corresponding values of potential difference V across the resistor are given below: Plot a graph between V and I and calculate the resistance of that resistor.
Question 8: When a 12 V battery is connected across an unknown resistor, there is a current of 2. Question 9: A battery of 9 V is connected in series with resistors of 0. Answer: Since all the resistors are in series, the same current, 0. Question Several electric bulbs designed to be used on a V electric supply line, are rated 10 W. Question A hot plate of an electric oven connected to V line has two resistance coils A and B, each of 24 Q resistance, which may be used separately, in series, or in parallel.
Question Two lamps, one rated W at V, and the other 60 W at V, are connected in parallel to electric mains supply.
Question An electric heater of resistance 8 f2 draws 15 A from the service mains 2 hours. Question Explain the following. Answer: a It has high melting point and emits light at a high temperature. Each of them dissipates energy and can withstand a maximum power of 18 W without melting.
Find the maximum current that can flow through the three resistors. Question 2: Should the resistance of an ammeter be low or high? Give reason. Answer: The resistance of an ammeter should be low so that it will not disturb the magnitude of current flowing through the circuit when connected in series in a circuit.
Question 3: How does use of a fuse wire protect electrical appliances? Answer: The fuse wire is always connected in series with the live wire or electrical devices. If the flow of current exceeds the specified preset value due to some reason, the heat produced melts it and disconnects the circuit or the device from the mains.
In this way, fuse wire protects the electrical appliances. Question 4: What is electrical resistivity? In a series electrical circuit comprising a resistor made up of a metallic wire, the ammeter reads 5 A.
The reading of the ammeter decreases to half when the length of the wire is doubled. Answer: The resistance offered by a metallic wire of unit length and unit cross-sectional area is called electrical resistivity. Hence, when the length of wire is doubled, the resistance becomes double and current decreases to half. Calculate the resistance of the electric lamp. Question 6: Why is parallel arrangement used in domestic wiring? Answer: Parallel arrangement is used in domestic wiring because i Each appliance gets the same voltage as that of the mains supply.
Question 7: B 1, B 2 and B 3 are three identical Ncert Solutions Class 10th Physics Electricity Review bulbs connected as shown in figure. When all the three bulbs glow, a current of 3A is recorded by the ammeter A.
Answer: i Since B 1 ,B 2 and B 3 are in parallel, the potential difference across each of them will remain same. So when the bulb B 1 gets fused, B 2 and B 3 have the same potential and continues with the same energy dissipated per second, i. Question 1: Three incandescent bulbs of W each are connected in series in an electric circuit.
In another circuit, another set of three bulbs of the same wattage are connected in parallel to the same source. Justify your answer. Will the rest of the bulbs continue to glow in each circuit? Answer: a The bulbs in the two circuits will not glow equally bright as the current through them is not the same. While the rest Ncert Solutions Class 10th Physics Electricity Unit of bulbs in parallel circuit will continue to glow without getting disturbed because in parallel combination, current gets additional paths to flow.
Question 2: Find out the following in the electric circuit given in Ncert Solutions Class 10th Physics Electricity Us figure: Answer: e No difference, since the ammeters are connected in series and same current will pass through them, so reading of both ammeters will be same. Question 1. To determine the equivalent resistance of two resistors when connected in series, a student arranged the circuit components as shown in the diagram.

Question 4. An ammeter has 20 divisions between 0 mark and 2A mark on its scale. The least count of ammeter is a 0. Question 5. A student finds that there are 20 divisions between zero mark and 1V mark of a voltmeter. The least count of voltmeter is a 0. Question 6. The current flowing through a resistor connected in an electric circuit and the potential difference applied across its ends are shown in figure alongside.
Question 7. Question 8. In an experiment on studying the dependence of the current I flowing through a given resistor on the potential difference V applied across it, a student has to change the value of the current. For doing this, he should change the a number of cells used b resistor itself c ammeter used in the circuit d Voltmeter used in the circuit Answer: a If we change the number of cells in electric circuit, the potential difference will change and as a result current flowing in the circuit changes.
Question 9. A milliammeter had graduations marked 0, , , , and The space between 0 mark and mark is divided into 20 divisions. Question To determine the eguivalent resistance of two resistors connected in series, a student prepared two electric circuits, correct reading of ammeter in the circuits is [CCE ] a In circuit I, 1.
