Electricity and Magnetism definitions

A device used to show the presence of electric charge

• Electroscope
• Capacitor
• Voltmeter
• Resistor

The relationship between the voltage, V, current, I, and resistance, R in an ohmic circuit.

• Newton's Law

• Einstein's Law

• Sabin's Law

• Ohm's Law

The quality of materials that are weakly repelled by other magnets and are magnetic only when in an external magnetic field

Example.
