Homework Equations
Pe= E x Is
Is = V/R
The Attempt at a Solution
I figured that in order to find the power delivered by the source, I would have to use the equation: Pe= E x Is.
E is already given to me.. 60.
That means I just have to find Is. I used the formula Is= V/R and applied it to each resistor to find the current. Here is what I got:
I1= 12A
I2= 30 A
I3= 7.5 A
I4= 3 A
I5= 5 A
I added these values up to find Is and got 57.5 A. Now I apply the formula Pe= E x Is (Pe= 60 x 57.5) and got 3450 Watts for the power delivered by the battery.
However.. The correct answer is 1.56 kW
Am I using the wrong formula completely? Where did I go wrong?
Thanks!
