Electrical resistor

Resistance of the electrical wires.

Faraday's law (quantitative)

This visual studies the value of the induced current, which is produced when the homogeneous field B (perpendicular to the visible surface) is altered or the surface area of the circuit is altered by ...

Faraday's law

When the magnetic flux which travels through a coil varies, an electric current is generated in the latter which can light up a bulb.

Voltmeter

The voltmeter is an instrument which measures voltages (tensions or differences of potential) between both ends of an element in a circuit through which there is an electric current circulating.

ammeter

This visual shows you how to insert an ammeter and how to use it in a circuit.

alternator

Basis of the alternator

self-inductance

When an electric current of variable intensity circulates through a coil an induced current originates inside it.

Mutual induction

A light bulb in a circuit near another circuit with a battery, a coil and a rheostat, can light up even though ITS OWN CIRCUIT HAS NO BATTERY.
