Capacitor charge time calculation - time constants

The video tutorial explains the behavior of a capacitor in a series circuit with a resistor and switch. It covers the concept of time constants, showing how the capacitor charges and discharges over time, following an exponential curve. The tutorial provides calculations for time constants and voltage levels at different stages, illustrating how changes in resistance and capacitance affect the charging and discharging times. Example scenarios demonstrate these principles in practical applications.

What happens to the voltage across a capacitor when a switch is closed in a circuit with a resistor?

Explain the concept of time constant in relation to a capacitor charging circuit.

Calculate the voltage across a capacitor after 5 seconds if it has a time constant of 1 second.

How does the size of the capacitor affect the time taken to charge it?

Describe the voltage levels at each time constant during the charging of a capacitor.

What occurs to the current in the circuit as the capacitor charges?

How does the discharging process of a capacitor differ from the charging process?
