Is the following statement true or false? the time constant of an rc circuit is the time it takes to completely charge or discharge the capacitor. o true false

FALSE

Explanation:

As we know that equation for charging of a capacitor is given by

now at t = 0 we can say there is no charge on the capacitor

now as the time will increase the value of charge will increase on the plates of capacitor

now after t = 1 time constant

we will have

so after one time constant the capacitor will charged upto 63% of its maximum value.

It is due to the relative velocity.

When you go opposite, the velocities of both buses get added increasing relative velocity

When we overtake it (in same direction) then the velocities get subtracted. Hence reducing relative velocity
