Question

A current of 5 amp flows through a wire whose ends are at potential
difference of 3 V.calculate the resistance of the wire.

Answer 1

Answer:

Given,

Current = 5 A

Potential Difference = 3 V

By Ohm's law V = IR

Then,

Put the values:

3=5R

R = 3/5 = 0.6 Ω

Explanation:

mark me as brainliest

Answer 2

Answer:

Explanation:

P.d.= 3V

I = 5A

R=P.d/I

R=3V/5A

R=0.6Ω          (Ω pronounced as ohm=V/I)
