ELECTRICITY & HYDRAULICS

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

  • VOLTAGE is like the pressure that pushes water through the hose. It is measured in volts (V).
  • CURRENT is like the diameter of the hose. The wider it is, the more water will flow through. It is measured in amps (I or A).
  • RESISTANCE is like sand in the hose that slows down the water flow. It is measured in ohms (R or Ω).

Voltage, current, and resistance are all related. If you change one of them in a circuit, the others will change, too. Specifically, voltage is equal to current multiplied by resistance (V = I x R). Thinking about water, if you add sand into the hose and keep the pressure the same, it’s like reducing the diameter of the hose… less water will flow.
