Mini-Quiz: Ohm's Law for Simple Electric Circuits

by Ron Kurtus (updated 30 May 2023)

Take this Mini-Quiz to check your understanding of the lesson material.

1. What does the letter I stand for in Ohm's Law?




2. What is Ohm's Law used for?

To calculate the third unknown, if you know the other two parameters

To determine if it is an AC or DC circuit

To give Ohm credit for his good work

3. What can prevent Ohm's Law from applying in an AC circuit?

Ohm's Law always applies to any electric circuit

Using bare wires

If there is a capacitor or inductor in the circuit

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Be determined to do your best
