Question

Which of the following is the correct Ohm's law formula used to find resistance?

A. R = E/I
B. R = EI
C. R = PI
D. R = I/E

Answer 1

Hey there!

Let's define our variables:

E- Voltage

I- Current

R- Resistance

A method that you can use to find Voltage, Resistance, and Current is a bit confusing, but looks like this:

V

I R

If you want resistance, you cover the R, and you get V/I. If you want Voltage, you cover the V and get IR. It's a very helpful tool.

Hope this helps!
