The time constant is defined as the time required by the capacitor _.
Correct answer: A. To deposit 63% of the equilibrium charge
- A. To deposit 63% of the equilibrium charge
- B. To deposit 36% of the equilibrium charge
- C. To deposit 63 times of the equilibrium charge
- D. To deposit 36 times of the equilibrium charge
Explanation
The meaning of time constant is the time taken by the capacitor to be charged to about 63.2% of its full value through a resistor connected to it in series. Hence option A is correct.

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.
