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.

Understanding DC Power:

DC power has many applications, including:

Powering electronic devices: Many electronic devices, from little devices like laptops and cellphones to larger ones like televisions and refrigerators, are powered by DC electricity. 

Renewable energy systems: Renewable energy devices like solar panels and wind turbines use DC power to produce electricity. 

Automotive systems: Numerous vehicle systems rely on DC power to operate the engine, charge the battery, and power accessories like the lights and radio.

Medical devices: Insulin pumps, implanted cardioverter-defibrillators, pacemakers, and other medical equipment all use DC power. 

DC power has a wide range of practical uses, but it is also employed in numerous scientific and research situations, such as: 

Electrical engineering: Circuits and systems involving electricity are tested and examined using DC power.

Physics and chemistry: The behavior of electrical charges and the characteristics of materials are studied with DC power. 

Astronomy: Several astronomical devices, such as spectrometers and telescopes, require DC power. 

All things considered, DC power is a crucial part of many contemporary technology and affects our day-to-day existence greatly. 

The quantity of electrical energy that an electric circuit can transfer in a given amount of time is known as electric power. The watt, or one joule per second, is the SI unit of power. Using the provided voltage and current numbers, you can use our user-friendly online DC power calculator to calculate the power output of your circuit. You just need to enter the voltage in volts and the current in amps into this free DC current calculator to get the power output in watts.

Note : Don’t end with comma ( , )

To Find
Voltage (V)
Current (I)
Power (P)


\[P = V × I \\V = \frac{P}{I} \\I =\frac{P}{V}\]


  • P = Power
  • V = Voltage
  • I = Current
