Find what percentage of the maximum voltage is on capacitor

Reference no: EM13667118

For charging process, the voltage across the capacitor as a function of time is given by Vc = ε[1-exp(-t/τ)]

a) When the time is twice the time constant, find what percentage of the maximum voltage is on the capacitor?

b) Compute the time it took in terms of the time constant, for the voltage across the capacitor to be 30 percent of the maximum voltage.
