The Attempt at a Solution


I used the Pythagorean theorem Vs= the square root of Rv squared plus (Lv-Lc) squared and came up with a voltage source of 100 volts AC. Right??
So how do I figure the voltage between A,C and B,D? I have come up blank on this one, I don't even know where to start.

What do you know about the difference between inductive reactance and capacitive reactance?
 
OK Guys here are the answers I was given after the re-test, Thanks for all the help guys

1 source voltage 100 volts AC
2 Between A and C 0 volts AC
3 Between B and D 141 volts AC
4 Between A and D 100 volts AC

I say that the answers to 2 & 3 should be switched!

2 Between A and C 141 volts AC

3 Between B and D 0 volts AC
