How many time constants does a capacitor take to fully charge?

After five time constants, the capacitor is considered fully discharged, as the remaining charge is around 0.7%. So, when questioning how many time constants for a capacitor to fully charge it takes, the answer applies to its discharge the same:

What determines the charge time of a capacitor?

So, the charge time of a capacitor is primarily determined by the capacitor charge time constant denoted as ? (pronounced tau), which is the product of the resistance (R) in the circuit and the capacitance (C) of the capacitor.

Why does a capacitor take a long time to charge?

As we know a capacitor when connected to a power supply with take some time to charge. Since all the circuits have some kind of resistance in them, whether it's the resistance of the connecting wires or the internal resistance of the power source such as batteries we can always consider that a resistor is present in series with a capacitor.

How long does it take a resistor to charge a capacitor?

If a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across it reaches that of the supply voltage. The time required for the capacitor to be fully charge is equivalent to about 5 time constants or 5T.

How long does a capacitor take to charge and discharge?

This charging (storage) and discharging (release) of a capacitors energy is never instant but takes a certain amount of time to occur with the time taken for the capacitor to charge or discharge to within a certain percentage of its maximum supply value being known as its Time Constant ( τ ).

Can a capacitor be charged and discharged?

As a capacitor can be charged, it can also be discharged by replacing the battery in the electric circuit. The time for discharge follows analogous, where the time constant correlates to the charge percentage drop of about 37%. Similar to the charging, the discharging follows an exponential curve as the flowing current decreases over time.
