An explanation of a cirucits current and voltage with resistors in parallel. [12:20]

What is the process that provides voltage in a battery cell? Check out this virtual lab.

What is the highest voltage that can be had with one capacitor? Find an illustration of it here.

Demonstrating that voltage is an intensive property by calculating the voltage and change in Gibbs free energy for a half reaction. [5:22]

In this video, David from Khan Academy derives the formula to find the power used by a resistor. [10:42]

Learn about the instruments we use to measure voltage and current. [8:17]

A video explaining how voltage is created within in a battery by the chemicals inside. Learn how the energy in the battery allows current to flow through a circuit to create electricity. [4:06]

This lesson will explain how to calculate voltage, current, and resistance in simple electric circuits. It is 1 of 4 in the series titled "Electric Circuits."

Mr. Andersen describes the relationship between voltage, current and resistance in an electric circuit. Ohm's Law is introduced through a circuit simulation.
