Question

The instantaneous charge on capacitor in two discharging RC circuits is plotted with respect to time in figure. Choose the correct statement(s) (where E1 and E2 are emfs of two DC sources in two  different charging circuits and capacitors are fully charged).
                                                 

Options

A.R1C1 > R2C2
B.
C.R1 > R2 if  E1 = E2
D.C2 > C1 if E1 = E2

Solution

t1 > t2
R1C1 > R2C2    for same qmax
q01 = q02     ⇒  E1C1 = E2C2
If E1 = E2  ⇒  C1 = C2 ⇒ R1 = R2 .
