What is Ohm's law?

Electricity isn't magic—it's more like water movin' through a system of tubes. Think of the VOLTAGE SOURCE as a battery providin' the PUSH, or electrical pressure, that gets everythin' movin'. That energy needs a place to go, so it travels through the CONDUCTIVE PATH, which is like a clear pipe lette'n electrons flow freely. But sometimes we need to slow things down, and that's what the ELECTRICAL RESISTOR does by squeezin' the path to limit how much can get through at once. The actual speed and amount of electricity movin' is the CURRENT FLOW, which we measure in AMPS. When you put it all together, you get OHM'S LAW: Voltage equals Current times Resistance. It's the perfect math recipe to calculate exactly how much power a circuit is usin'! Tiny Concepts.
