Question

(b) Three batteries A,B and C have their negetive terminals connected together. Between the positive terminals of A and B there is a resistor of 0.5 ohm and between B and C there is a resistor of 0.3 ohm. The specifications of the batteries A, B and C are follows:

Battery A 105 V, Internal resistance 0.25 ohm

Battery B 100 V, „ „ „ 0.2 ohm

Battery C 95 V, „ „ „ 0.25 ohm

Determine the current values in the two resistors and the power dissipated by them.
