DC Power

Calculate DC power, voltage, or current using P = V × I.

In contrast to Alternating Current (AC), which alternates direction on a regular basis, DC power is electrical energy that flows steadily in a single direction within a circuit. It is frequently utilized in a variety of electronic systems and devices and is produced by sources like batteries, solar cells, and rectifiers.

DC power is mostly used to supply a steady and dependable electrical energy source for electronic systems and gadgets. As the foundation for numerous vital operations in contemporary technology, it provides a steady stream of energy to run everything from massive industrial machinery to tiny electronic devices.

About This Calculator

The quantity of electrical energy that an electric circuit can transfer in a given amount of time is known as electric power. The SI unit of power is the watt (W), or one joule per second.

This user-friendly online DC power calculator computes the power output of your circuit using the provided voltage and current values. Simply enter the voltage in volts and current in amps to get the power output in watts.

Formulas

P=V×IP = V \times I

V=PIV = \frac{P}{I}

I=PVI = \frac{P}{V}

where:

  • PP = Power (W)
  • VV = Voltage (V)
  • II = Current (A)

Inputs

DC voltage in volts

DC current in amps

DC power in watts

Results

Voltage and current must be greater than zero to solve for Power
