A : When two cells of equal EMF and equal internal resistances are connected is parallel with positive plate of the other than , the net EMF , of the combination will be equal to the EMF of each cell. R : Effective internal resistance of the parallel combination of two identical cells will be half of the internal resistance of each cell.

An ammeter and a voltmeter of resistance R connected in seires to an electric cell of negligible internal resistance. Their readings are A and V respecitvely. If another resistance R is connected in parallel with the voltmeter

An ammeter and a voltmeter of resistance R are connected in series to an electric cell of negligible internal resistance . Their readings are A and V respectively. If another resistance R is connected in parallel with the voltmeter , then

In the electric circuit shown each cell has an emf of 2 V and internal resistance of 1Omega . The external resistance is 2Omega . The value of the current is (in A)
