DC Power Calculator


About DC Power Calculator (Formula)

The DC Power Calculator is a tool used to compute the electrical power of a direct current (DC) circuit. The formula for calculating DC power is as follows:

DC Power (P) = Voltage (V) × Current (I)


  • DC Power (P): The amount of electrical power consumed or produced in the DC circuit, usually measured in watts (W).
  • Voltage (V): The potential difference across the circuit’s terminals, measured in volts (V).
  • Current (I): The flow of electric charge through the circuit, measured in amperes (A).

This calculation helps determine how much electrical energy is used or generated by a device or component in the DC circuit. If the voltage and current are in phase (meaning they peak and trough simultaneously), the power is positive and represents power consumption. If the voltage and current are 180 degrees out of phase (meaning they peak and trough at opposite times), the power is negative and represents power generation.

The DC Power Calculator is widely used in electrical engineering and electronics to analyze the efficiency and performance of DC circuits, devices, and components. It’s also crucial in designing and optimizing power systems to ensure proper functioning and energy management.
