Concept of speed and mass of the electrons
The educational resource shows a visual about the intensity of the electric field:What are the lines of force like in a field created by two electric charges?
The electricity consumption
The movement of the electrons inside an electrical conductor of oscillating form.
Resistance of the electrical wires.
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 ...
When the magnetic flux which travels through a coil varies, an electric current is generated in the latter which can light up a bulb.
Measure of the voltage
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.
