which allows us an easy way of describing alternating current, along with its frequency and phase.

How do you understand electricity?

The three most basic components of electricity are voltage, current, and resistance.

  1. VOLTAGE is like the pressure that pushes water through the hose. It is measured in volts (V).
  2. CURRENT is like the diameter of the hose. …
  3. RESISTANCE is like sand in the hose that slows down the water flow.
