A sinusoidal alternating potential difference is rectified and smoothed using the circuit in Fig. 5.2. The capacitor has capacitance C of 85 μF and the resistor has resistance R. The effect of the capacitor and the resistor is to produce a smoothed output potential difference V_OUT. The difference between maximum and minimum values of V_OUT is 2.0 V.
On Fig. 5.1, draw a line to show V_OUT between times t = 1.0 ms and t = 5.0 ms.
