Question

A 4v battery is connected to a lamp of resistance 4 Ohm. Calculate the current through the lamp.

Answer 1

Hey there !

Solution:

According to Ohm's Law,

Potential Difference is equal to Current multiplied by Resistance. That is,

V = I R

So given that, V = 4 V and R = 4 Ω. We are asked to find the I ( current ) in the resistor.

V = I R

=> I = V / R

=> I = 4 / 4

=> I = 1 A

Hence the current flowing through the resistor is 1 ampere or 1 A.

Hope my answer helped !
