What is the difference between voltage, amperage and wattage?
Here is a simple way to remember the difference. Think of a car as a metaphor: (1) Voltage can be considered the speed of which the current flows (or the accelerator); (2) Amperage is the amount of power the system can accommodate (or the car engine); (3) Wattage is the unit of measurement of the light bulb itself (or the gas consumed).
