Superposition Theorem

Power to the people who understand electricity. A simple experiment teaches pupils how to set up an electric circuit that includes a solar module and how to measure voltage and current using a multimeter. They calculate power and...

In this voltage, current and resistance worksheet, students answer 21 questions about voltage, current and resistance. They find the current in batteries, they find the voltage in a resistor and they identify the voltage in circuits.

In this resistance activity, learners read about voltage, current and resistance in order to determine the equation for resistance. They solve fourteen problems for resistance, current or voltage.

Wow! Here is a coherent and cleverly designed tool for teaching physical scientists about electric circuits. Animations help learners to visualize what is happening within the parts of a circuit. Components are displayed to teach them...

Necessary vocabulary for exploring electric current is detailed in these slides. Circuits, voltage, wet and dry cell and batteries are defined, making this a great overview on the subject. It could also serve as a complement to a lesson,...

Here's a video that explains the difference between series and parallel circuits, including the impacts of each on current and voltage.

This brief video provides definitions for charge, current, and voltage and compares and contrasts these terms. The video also discusses coulomb, amps, and joules. 

Join the resistance—Ohm! Scholars apply Ohm's Law to problems of increasing difficulty as part of a series on electric circuits. The lesson begins with simply doubling and tripling voltage or resistance. It ends with having pupils solve...

Don't know how to make the initial connection on electric circuits? This lesson provides the background to present the introductory vocabulary to learning about electric circuits. It is organized in a meaningful progression with an...

Resistance is not futile ... it is voltage divided by current. Scholars apply their knowledge to a series of ranking puzzles. First, they consider wires of varying lengths and then wires of varying cross-sectional areas. Finally, they...
