Question

The current flowing through a resistor is 0.8 A when a potential difference of 20volt is applied, calculate the resistance?

Answer 1

Current = I = 0.8 A

Potential Difference = V = 20 V

Resistance = ?

Using Ohm's Law,

V = IR

R = V / I

R = 20 / 0.8

R = 25 ohm

Answer 2

Answer:

Answer is 25 ohm as by applying formala of V = IR or R = V/I
