Question

a wire having resistance of 20 ohm carrying current of 9 ampere what is the potential difference across its ends​

Answer 1

Answer:

180 Volt

Explanation:

voltage = current * Resistance

so current is 9 amp and Resistance value is 20 ohm.

so the voltage is 180 volt

Answer 2

Answer:

We know

V= i×R

So, given

I=9 ampere

R=20ohm

Hence put the value

V=20×9

=180 volt
