An electric circuit is connected as illustrated above. Determine the equivalent e.m.f and current flowing through the circuit respectively, neglecting the internal resistance of the cells
2V, 1.0A
2V, 4.0A
6V, 0.3a
6V, 3.0a
Correct answer is A
cells in V = voltage of the cell
= 2V
I = \(\frac{v}{R} = \frac{2}{3}\)
= 1A
