Question

Find the potential difference required to flow a current 200 mA in a wire of resistance 20 ohm​

Answer 1

Answer:

V=IR.

I=200 mA=0.2A

R=20

so,V=0.01volt

Answer 2

Answer:

Current= 200mA

100mA= 0.1Ampere

200mA= 0.2Ampere

resistance=20ohm

Explanation:

As we know

I=V/R

0.2=V/20

20×0.2=V

4=V

HENCE THE POTENTIAL DIFFERENCE THAT REQUIRED IS 4V.

I HOPE IT HELFUL
