Question

what potential difference must be applied across a 10ohm wire in order that a current of 2.5A flows through it​

Answer 1

Answer:

From ohm's law we know that

V = IR

where V = potential diff.

I = electric current

R= electrical resistance

=> V = (10)(2.5)

=> V = 25V

Answer 2

Answer:

25 V

Explanation:

V=IR

I=2.5A

R=10'Ω

V=IR= 10 x 2.5 =25 V
