A capacitor with a capacitance of is connected to a battery via a resistor. Which of the following statements are true regarding the charge stored on the capacitor during the initial ?
Options
- AIt is smaller than the charge stored in the subsequent .
- BIt is larger than the charge stored in the subsequent .
- CIt is larger than the charge stored in the subsequent .
- DIt is larger than the charge stored in the subsequent .
Correct answer
D. It is larger than the charge stored in the subsequent .
Step-by-step solution
The time constant of the circuit is given by .
Substituting the given values:
The charge on the capacitor as a function of time is , where is the maximum steady-state charge.
The charge stored during the initial () is:
The maximum possible charge that can be stored in all subsequent time ( to ) is:
Since , the charge stored in the initial is strictly greater than the total charge stored in any subsequent time interval, regardless of its duration.
Therefore, the charge stored in the initial is larger than the charge stored in the subsequent , , , and .
