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 and are emfs of two DC sources in two different charging circuits and capacitors are fully charged).

A
$${ R }_{ 1 }{ C }_{ 1 }>{ R }_{ 2 }{ C }_{ 2 }$$
B
$$\frac { { R }_{ 1 } }{ { R }_{ 2 } } <\frac { { C }_{ 2 } }{ { C }_{ 1 } } $$
C
$${ R }_{ 1 }>{ R }_{ 2 }$$ if $${ E }_{ 1 }={ E }_{ 2 }$$
D
$${ C }_{ 2 }>{ C }_{ 1 }$$ if $${ E }_{ 1 }={ E }_{ 2 }$$
Solution
