Total Power Formula
The following formula is used to calculate the Total Power.
Pt = I^2*R1+I^2*R2+I^2*R3
- Where Pt is the Total Power (watts)
- I is the current (amps)
- R1 is the up to 3 different resistances (ohms)
How to Calculate Total Power?
The following two example problems outline how to calculate the Total Power.
Example Problem #1:
- First, determine the current (amps). In this example, the current (amps) is measured to be 10.
- Next, determine the different resistances (ohms). For this problem, the different resistances (ohms) are calculated to be 50,30, and 20.
- Finally, calculate the Total Power using the formula above:
Pt = I^2*R1+I^2*R2+I^2*R3
Inserting the values from above and solving the equation with the imputed values gives:
Pt = 10^2*50+10^2*30+10^2*20 = 10,000 (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:
current (amps) = 50
3 different resistances (ohms) = 6,7,8
Entering these values into the formula or calculator above gives us:: Pt = 50^2*6+50^2*7+50^2*8 = 52,500 (watts)
