Question

When an electric lamp is connected to 12 V battery, it draws a current of 0.5 A. The power of the lamp is :; A. 0.5 W; B. 6W; C. 12 W; D. 24W

Answer 1

Explanation:

At first we have to find resistance (r)

volt is 12

current is 0.5amp

r is v/I 12/0.5

Power is 12x12x0.5/12

is equal to 6

hope this answer will satisfy you
