Mini-Quiz: Basic Units of Simple Electrical Circuits

by Ron Kurtus (9 December 2013)

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



1. What is an ampere?

It is the potential energy across two infinite wires

It is the unit of electrical current

It is the total number of electrons in a wire

2. What is the relationship of volts and energy?

A volt is a joule of energy per coulomb of charge

Volts have nothing to do with energy

The energy of volts creates resistance in ohms

3. What is an ohm the measurement of?

Resistance to electrical current

Resistance to electrical voltage

Energy in a wire

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.


It is good to learn the basics
