Question

If a wire has resistance 100 ohm and current through it is 0.5 A the potential difference across the wire must be ....
100v
50v
500v
0.5vplr​

Answer 1

Answer:

50 volt

Explanation:

Use ohms law

V = R I

V = 100 × 0.5

V = 50

Answer 2

Answer:

50v

Explanation:

v= ir

0.5×100

=5/10×100

=50v
