Question

If you have a series circuit with 5A of current before a 4 Ohm resistor, what is the current after the resistor?

Answer 1

In series connection, the current will be the same through all the resistors

Hence the current after the resistor will be 5A itself

I = 5A

R = 4Ω

V = IR

V = 5*4

V = 20V

The potential difference across the resistor will be 20V
