The transformer modifies the voltage of a current.

The educational resource shows a visual about the movement of electric charges: the visual shows a capacitor where the intensity of an electric field bewteen its plates is practically constant. This area is a good place to study how the charges inside an electric field move.

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

Type of electronic test instrument that allows observation of varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time.

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