For the circuit shown to the right, determine the magnitude of the currents 12, /3, and l4 passing through batteries 2, 3, and 4, respectively. In each case, determine whether the battery is supplying power or being charged. The batteries and resistors in the circuit are assumed to be ideal and have the following properties E.= 28.5 V 1.50 V 18.0 V 1.50 V R, 15.0 R 10.0 R, 85.0 Number supplying power being charged 2 Number supplying power being charged 3 Number supplying power being charged 4Explanation / Answer
Applying KVL in right side loop:
E1 - E2 - i2 R2 - E4 - i2R2 = 0
28.5 - 1.5 - 10i2 - 1.5 - 15i2 = 0
i2 = 1.02 A ........Ans ( being charged)
Applying KVL in left side loop:
E3 - i2R3 - E4 = 0
18 - 1.5 = 85i3
i3 = 0.19 A ......Ans (Supplying Power)
Applying KCL:
i4 = i2 + i3 = 1.21 A (being charged )
