## NCERT Solutions for Class 10 Science Chapter 12 : Overview

In the below section, we have given the list of all exercises from 12.1 to 12.8, of which Ex 12.6 and 12.7 have sub-units. Before getting into the details of NCERT Solutions for Class 10 Science Chapter 12 (Electricity), let us have a quick look at the different sections in the chapter.

### In-text Solutions for Class 10 Science Chapter 12

In this section, you will find the solved exercises for Class 10 Science Chapter 12. You can also download NCERT Solutions for Chapter 12 – Electricity in PDF and refer to it offline.  Q.7. Compare the power used in the 2 Ω resistor in each of the following circuits: (i) a 6 V battery in series with 1 Ω and 2 Ω resistors, and (ii) a 4 V battery in parallel with 12 Ω and 2 Ω resistors.
Solution:
(i) Power used, P=I2R=V2R
Here, Iis the current through resistor and Vis the potential difference across the resistor,
P=61+22×2=8 W
(ii)Power used, P=I2R=V2R Here, I is the current through resistor and Vis the potential difference across the resistor.
P=422=8 W
Power consumed by 2 Ω resistor in both cases is the same and is equal to 8 W.
Q.8. Two lamps, one rated 100 W at 220 V, and the other 60 W at 220 V, are connected in parallel to the electric mains supply. What current is drawn from the line if the supply voltage is 220 V?
Solution:
Given,
Rated power of first bulb, P1= 100 W and Rated voltage, V= 220 V
Rated power of second bulb, P2=60 W and Rated voltage, V= 220 V Resistance of the first lamp, R1=V2P1=2202100=484 Ω Resistance of the second lamp, R2=V2P2=220260=806.67 Ω If these two resistors are joined in parallel, equivalent resistance, Req=484×806.67484+806.67
Current drawn from the line, I=VReq ⇒I=220484×806.67484+806.67=220302.5=0.727 A
