Question

A battery-powered alarm clock has a resistance of 85 2. A current flows in the circuit of 0.26 amps. What is

the voltage of the battery?

Answer 1

v= ir

Here, I = 0.26

R = 852

So,

v = 0.26 x 852

= 221.52 V

If R = 85.2 and I = 0.26,

V= ir

v = 0.26 x 85.2

v = 22.152.

Hope it helps.
