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