Q. In a circuit, the time required for the charge on a capacitor to build up to a given fraction of its steady state value, is independent of:

Current Electricity Report Error

Solution:

The charge on capacitor as a function of time is given as

Here is termed as steady state charge or equilibrium charge so if we use then from above relation we get time taken for charge to grow upto f fraction of its steady state value which is given as which is independent of applied EMF.
