The most important Electrical Law is the Ohms Law, a proper understanding of which can help you make many designs. Troubleshooting Home Appliances or understanding Household Wiring is easy if you master this.

Volts is analogous to the pressure of a water in an Overhead Tank. The water head or height is like Voltage. The Pipe diameter and bends are like wire and its resistance, a water tap like a wirewound potentiometer. The rate of water flowing from the tap is like the flow of electric current in a wire.

The water drops are similar to units of charge, the quantity of water filled in a bucket is like the amount of charge stored in a small capacitor. The Underground Sump can be compared to a Big capacitor. The evaporation of water is like leakage of charge thru the dielectric in a cap. If you use the running water to power a home made paddle wheel turbine; This is like simulating an electric motor or heater in a water circuit, the rotary power got, can be analogous to the heater’s watts..
