Question

the p.d. between the ends of a wire of resistance 5 ohm, if 720 columbs of charge passes through it per minute

Answer 1

Answer :-

The potential difference between the ends of a wire is 60 volts.

Explanation :-

Given :

Resistance (R) = 5 Ω

Charge (q) = 720 C

Time (t) = 1 minute = 60 sec

To find :

Potential difference between the ends of a wire.

Solution :

I = Q/t

I = 720/60

I = 72/6

I = 12 A

________________________________

V = IR

V = 12 × 5

V = 60 V

∴ The potential difference between the ends of a wire is 60 volts.
