Physics Electrostatics Potential & Capacitance Capacitance MCQ (Single Correct)

The charge on capacitor in two different RC circuits 1 and 2 are plotted as shown in figure.

Choose the correct statement(s) related to the two circuits.

Both the capacitors are charged to the same magnitude of charge

The emf's of cells in both the circuits are equal

The emf's of the cells may be different

The emf E 1 is more than E 2

Text Solution

Verified by Experts

The correct answer is:

CHECK THE SOLUTION.

(a, c)

q max = q 01 = q 02 = Both capacitors are charged up to the same magnitude of charge

t 2 > t 1

R 2 C 2 > R 1 C 1

q 01 = C 1 V 1 = q 02 = C 2 V 2

C 1 ≠ C 2

So, V 1 ≠ V 2 .
