Output Power Formula
The following formula is used to calculate the Output Power.
Po = Pi * E/100
- Where Po is the Output Power (watts)
- Pi is the input power (watts)
- E is the efficiency (%)
To calculate the output power, multiply the input power by the efficiency.
How to Calculate Output Power?
The following two example problems outline how to calculate the Output Power.
Example Problem #1:
- First, determine the input power (watts). In this example, the input power (watts) is measured to be 502.
- Next, determine the efficiency (%). For this problem, the efficiency (%) is calculated to be 20.
- Finally, calculate the Output Power using the formula above:
Po = Pi * E/100
Inserting the values from above and solving the equation with the imputed values gives:
Po = 502 * 20/100 = 100.4 (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:
input power (watts) = 100
efficiency (%) = 20
Entering these values into the formula or calculator above gives us::
Po = 100 * 20/100 = 20 (watts)
