This is going to be hard to explain, but here goes!
Four resistors, R1 = 30.0 ohm, R2 = 52.0 ohm, R3 = 93.0 ohm and R4 = 17.0 ohm, are connected to a battery with a terminal voltage of 18.0 V, as shown in the figure below.
|___R4____ -(18 V)+____|
(that was the best i could do..)
Determine the power lost in the R2 = 52.0 ohm resistor.
