Enter the direct current (amps) and the direct voltage (volts) into the calculator to determine the DC Power.

## DC Power Formula

The following formula is used to calculate the DC Power.

Pdc = Idc * Vdc
• Where Pdc is the DC Power (watts)
• Idc is the direct current (amps)
• Vdc is the direct voltage (volts)

To calculate the DC power, multiply the direct current by the direct voltage.

## How to Calculate DC Power?

The following two example problems outline how to calculate the DC Power.

Example Problem #1:

1. First, determine the direct current (amps). In this example, the direct current (amps) is measured to be 51.
2. Next, determine the direct voltage (volts). For this problem, the direct voltage (volts) is calculated to be 6.
3. Finally, calculate the DC Power using the formula above:

Pdc = Idc * Vdc

Inserting the values from above and solving the equation with the imputed values gives:

Pdc = 51* 6 =306 (watts)

Example Problem #2:

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

direct current (amps) = 7

direct voltage (volts) = 40

Entering these values into the formula or calculator above gives us::

Pdc = 7 * 40 = 280 (watts)
