Q: An electric circuit is given below. V1 = 1 V and Resistance R = 1000 Ω. The current through the resistance R is very close to 1 mA and the voltage across point A and B, VAB = 1 V. Now the circuit is changed to another circuit where V2 = 5 V. The internal resistances of both the batteries are 0·1 Ω. The current through the resistance R is about:
(a)1·0 mA
(b)1·2 mA
(c)3·0 mA
(d)5·0 mA
