Qu’est ce que l’électricité ?

Electricity
is the flow of electrical energy through some conductive material.

Current
is a measure of the magnitude of the flow of electrons in a circuit. It is measured in Amperes. Using water flow as an analogy, current would be how much water (or electricity) is flowing past a certain point. The higher the amperage, the more water (or electricity) is flowing.

Voltage
is a measure of the electrical energy of a circuit. It is measured in Volts. In the water analogy, voltage would be the water pressure.

Resistance
is a measure of a material’s ability to oppose the flow of electricity. It is measured in Ohms. A sponge in the pipe would act as a resistor, limiting the current (and the voltage) flowing through the pipe.
