## 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)

## How to Calculate DC Power?

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

**Example Problem #1:**

- First, determine the direct current (amps). In this example, the direct current (amps) is measured to be 51.
- Next, determine the direct voltage (volts). For this problem, the direct voltage (volts) is calculated to be 6.
- 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)
