Two sources of equal $$emf$$ are connected to an external resistance $$R.$$ The internal resistance of the two sources are $${R_1}$$ and $${R_2}\left( {{R_1} > {R_1}} \right).$$ If the potential difference across the source having internal resistance $${R_2}$$ is zero, then
A
$$R = {R_2} - {R_1}$$
B
$$R = {R_2} \times \left( {{R_1} + {R_2}} \right)/\left( {{R_2} - {R_1}} \right)$$
C
$$R = {R_1}{R_2}/\left( {{R_2} - {R_1}} \right)$$
D
$$R = {R_1}{R_2}/\left( {{R_1} - {R_2}} \right)$$
