1. The problem statement, all variables and given/known data When testing the circuit of FIGURE 1 (a) it was found that the output shown in FIGURE 1 (b) was obtained when the input was connected to ground. explain why this was so and attempt an estimate of the capacitance values of C. 2. Relevant equations 3. The attempt at a solution estimating the waveform as 7ms the formula f = 1/T was used to get the frequency of 142.857Hz assuming C1 = C2 and R1 = R2 the formula f = 1/2πCR was used, rearranged into C= 1/2πfR to give capacitance as 111uF. any help is much appreciated in giving me any advice as to whather this is correct.
