Figures 4 and 5 represent the combination of two identical cells having negligible internal resistance.
(a)[1.0]
In which of the two combinations, emf of the battery is greater?
(b)[1.0]
When a resistor ‘$R$’ is connected between the terminals P and Q, $I_1$ and $I_2$ are the currents flowing through ‘$R$’ in Figure 4 and Figure 5 respectively. Obtain the ratio $\frac{I_1}{I_2}$.
Check your working with the Circuit solver (Kirchhoff's laws): every current, p.d. and power in a circuit of cells and resistors; equivalent resistance too.
