You have the following:
1.Two batteries one of emf 9V the other of emf 12V.The batteries are ideal(zero internal resistance)
2.Connecting wires of zero resistance
2.An ideal voltmeter(infinite resistance)
The batteries and voltmeter are all connected in parallel.What voltage will be measured when the batteries are connected positive terminal to positive terminal and negative terminal to negative terminal?What voltage will now be measured if one of the batteries is turned around to face the other way?
(Dont get too annoyed if you are unable to come up with an answer)
