An electric circuit is given below. V1 = 1V 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 = 1V. Now the circuit is changed to:
where value of V2 = 5V. The internal resistances of both the batteries are 0.1Ω . The current through the resistance R is about:
1
1.0 mA
2
1.2 mA
3
3.0 mA
4
5.0 mA
5
