95.MET March 2020 Q.10(b)

March 19, 2020 Posted by AK No comments
Three batteries A,B and C have their negative terminals connected together. Between the positive terminals of A and B there is a resistor of 0.5 Ω and between B and C there is a resistor of 0.3 Ω. 

Battery A        105 V       Internal resistance 0.25 Ω
Battery B        100 V       Internal resistance 0.2 Ω
Battery C          95 V       Internal resistance 0.25 Ω

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