Question

calculate the resistance of a conductor if the current flowing through it is 0.25A when the applied potential difference is 1.0V

Answer 1

As we know,
V=IR
Here,
V=1 V and I=0.25A
so,
By the formula,
R=1/0.25
R=4 Ohms

If you like my ans plz mrk it as brainliest.....

Answer 2

Given

v=1v;I=0.25A;R=? so,V=R/I. R=V/I. 1/0.25. R =4ohms
