Illustrated explanation of voltage, current, and resistance and the relationship between them.

This lab is designed to have students investigate the relationships between voltage, resistance and current in a parallel circuit with up to three passive components. The batteries in this simulation can be varied from ideal batteries to...

Explains what an LCR meter is and how it is used to measure the inductance, capacitance, and resistance of a circuit. Lists the different parameters of a circuit that it measures, describes two types of LCR meters, and gives definitions...

A teacher lesson plan is provided here. This page describes two activities in which the effect of multiple resistors on the current and overall resistance of both series and parallel circuits are investigated. Complete activity...

An interactive simulation that teaches about Ohm's Law, circuits, and current by observing how adjusting the voltage and resistance changes current according to Ohm's Law. This simulation can either be downloaded or played online and...

Brief explanation of Ohm's Law which provides the relationship between current, voltage, and resistance.

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow through the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change. Java...

This lab is designed to have students investigate the relationships between voltage, resistance and current in a series circuit with up to three passive components. The batteries in this simulation can be varied from ideal batteries to...

This tutorial illustrates why adding bulbs to a circuit makes all the bulbs dimmer.
