Question

how much electric current is produced on applying potential difference of 30 volts on a wire of resistance 20 ohms​

Answer 1

Answer:

i=v/r

i=30/20

i=1.5A

the current produced is 1.5 ampere

Answer 2

Answer:

1.5 A

Explanation:

We should know the concept of ohm's law.

• Ohm's law give us relation between current and potential difference.
• It state that at constant tempereture the current flowing in conductor is directly proportional to its potential difference at two cross end.

i.e.      V = I × R

  where ,

V is potential difference

R is resistance of conductor

and I is  electric current.

Given , R=20  ohms and V=30 volts.

I=V/R

I=30/20

I=1.5 A

Thus 1.5 A electric current is produced.
