In direct current (DC) circuits, the formula is simple: Power (watts) equals Voltage (volts) multiplied by Current (amps). Though they are related through the same physical system, they measure fundamentally different properties.
Understanding Voltage, Current, and Wattage in Electrical Systems
If voltage is the pressure, current is the volume of water moving through the pipe. Devices draw current to operate; the amount of amperage required depends on the energy demands of the device.
This pressure does not imply movement on its own; it simply creates the potential for current to flow when a circuit is completed. It is the unit of power, representing the rate at which energy is used or transferred.
Understanding Voltage Current and Wattage in Electrical Systems
When purchasing a new appliance, the wattage rating tells you how much your energy bill will increase, while the voltage requirement tells you if it is compatible with your home.
