Ohm’s Law Ohm’s Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. This was named for German physicist Georg Ohm (1789-1854) and addresses the key principles in circuits. If you know...

Voltage (V), Current (I) & Impedance (R) Relationship: A common analogy for the VIR relationship utilizes a standard garden hose. How it works: In this example, the spigot is the force or push (V) of the water flow (current – I) through the hose...

Voltage: This is Victor, he represents Voltage (V) today. The terms “amplitude” and “voltage” are often used interchangeably. Voltage is the force or push that causes electrons to move through a circuit. Current: These blue circles represent flow of electrons or...
