Any electrical engineers on the org?
Need some help on a homework problem, I think the prof missed an important step in how to solve some of these problems. Think you guys could lend a hand?
So far I have the equation V=RI (ohm's law) P=VI and E=PT
Only equations i have to work with.
heres the problem. Its in a closed circuit, couldnt get the picture up, if your really need to see it i can get it on here.
"A voltage source and two other elements are in series in a circuit. If Vs is 15 V, element 1 has 2 V across it, element 2 has 13 V across it, and 4 A are running through the circuit, find the power being dissipated or supplied by each of the three elements.
Ps= 60 W <---wrong
P1= 8 W <-- correct
P2= 52 W <---correct
I can get the voltages across the first and second element but not across the source. (its an independent voltage source)
