TS EAMCET · Physics · Alternating Current
In \(C R\)-circuit the growth of charge on the capacitor is
- A more rapid if the CR is smaller
- B more rapid if the CR is larger
- C independent of CR
- D independent of time
Answer & Solution
Correct Answer
(A) more rapid if the CR is smaller
Step-by-step Solution
Detailed explanation
(a) Growth of charge on capacitor in a \(C R\) circuit occurs as \(Q=Q_0\left(1-e^{-t / R C}\right)\) If product \(C R\) is small, then time constant for \(C R\) circuit is small and growth of charge will be more rapid.
