Question

A current of 0.2 ampere flows through a conductor of resistance 4.5 Omega.calculate the potential difference at the ends of the conductor

Answer 1

number if volts produced can be calculated by using the formula.
V = I * R
V = 0.2 * 4.5 = 9.00 OR 9 volts

Answer 2

given

current (I) = 0.2 A

resistance (R) = 4.5 ohm

potential difference (V) = ?

we know that

V = I×R

V = 0.2× 4.5

V = 0.90 v
