How much charge will have accumulated on the plates of a charging capacitor after a length of time equal to one time constant?

63% of the final charge

Explanation:

When a capacitor is connected to a battery/power supply, the capacitor charges following the exponential law:

where

is the final charge of the capacitor, which is

where C is the capacitance and the potential difference of the battery

t is the time

is the time constant of the circuit

Re-writing the equation,

After a time equal to one time constant,

Therefore the charge on the capacitor will be

Which means 63% of the final charge.

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
