A 100 Hz square wave, switching between 0V and 5V, is applied to a CR high-pass filter circuit as shown, The output voltage waveform across the resistor is 6.2V peak-to-peak, If the resistance R is 820Ω. then the value C is_________ μF. (Round off to 2 decimal places.)
Explanation:
For 1st half cycle, V0 = 5 – VC
For 2nd half cycle, V0 = -Vc
Vp-p = (5 – Vc min) – (-Vc max)
6.2 = 5 + Vc max – Vc min
Vc max – Vc min = 1.2 ………..(α)
For first half cycle i.e. 
………(i)
………(ii)
……….(iii)
From (ii),
Using equation (iii),
As
