Electrical is very easy
In the beginning, we will give a comparative example with a water pipe through which a certain amount of water flows under a certain pressure.
- Water pressure can be compared to voltage, measured in volts (abbreviated: V).
- The amount of water flowing over a certain time corresponds to an electric current, measured in amperes (abbreviated: A).
- Voltage and electric current, multiplied by each other, give the result of electric power with the unit of measure Watt (abbreviated: W).
- If voltage is divided by current, the result is resistance, measured in ohms (abbreviated: ohm). Resistance can be thought of as a stopcock in a water pipe. When the faucet is open, resistance is zero, water flows freely. If the tap is screwed on, the resistance rises to infinity, and the electric current dries up. Each current consumer is a resistance.
