Question

74.
An electric bulb has resistance 10 12, and the
voltage applied across it is 5 V. Find
(1) the current through the bulb
power of the bulb.
(Ans. 0.5 A, 2.5 W)
(2) the​

Answer 1

Explanation:

Given:-

V= 5v

R= 10

To Find:-

current I & power P

$i = \frac{v}{r} \\ i = \frac{5}{10} \\ i = 0.5a$
