If RC is small, then the capacitor will be charged and discharged
Correct answer: B. quickly
- A. slowly
- B. quickly
- C. with medium speed
- D. with constant speed
Explanation
When RC is small, the time constant τ=RC is small as well. A small time constant indicates that the capacitor will charge and discharge quickly because it takes less time for the capacitor to reach approximately its full charge or discharge.Incorrect options: (a) A small RC time constant implies a rapid charging and discharging process, not a slow one.(c) and (d) These options do not reflect the behavior of a capacitor in relation to the time constant.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
