Question

potential difference is 20 v and electric current produced is 3 ampere when passed through a resistor. what will we electric current produced when potential difference is 3oV and passed through same resistor. ​

Answer 1

V=IR

R=V/I

R=20/3

R=6.67ohms

I=V/R

I=30/6.67

I=4.5

Answer 2

4.5 is the answer u have doubt u can
