please solve quickly. Measuring CapacitanceOne way to measure capacitance is to apply a voltage step to an RC circuit with aknown resistance R and observe the step response in the time domain. Figure 2ashows one approach using a lowpass RC circuit; the delay tp from the VSTEP transitionto the 50% point of the ve waveform can be used to determine the capacitance if R isknown. Figure 2b shows another approach using a highpass RC circuit; in this case thepulse width tw at the 50% point of the vg waveform can be used to determine thecapacitance if R is known.Figure 2a. Step response of RC lowpass.VSTEPRVSTEPVctoVcFigure 2b. Step response of RC highpass.VSTEPVSTEPRVRVRtwFor the circuit of Figure 2a, find an equation providing C. given R and tp. Forthe circuit of Figure 2b, find an equation providing C, given R and tw.In each case, for values of R- 10k2 and C = 100PF, find the value you wouldexpect for tp and tw.P2.!!
