FM21 P42 Q10 Half-Wave Rectification & Smoothing | Feb/March 2021 | Cambridge A Level 9702 Physics

9702/42/F/M/21: The output potential difference (p.d.) of an alternating power supply is represented by V = 320sin(100πt) where V is the p.d. in volts and t is the time in seconds. (a) Determine the root-mean-square (r.m.s.) p.d. of the power supply. (b) Determine the period T of the output. #9702m21p42 #A2acGraphsP4 (c) The power supply is connected to resistor R and a diode in the circuit shown in Fig. 10.1. (i) State the name of the type of rectification produced by the diode in Fig. 10.1. (ii) On Fig. 10.2 sketch the variation with time t of the p.d. VR across R from time t = 0 to time t = 40ms. (iii) On Fig. 10.1, draw the symbol for a component that may be connected to produce smoothing of VR. #A2rectificationCircuitP4 #A2smoothingP4 #Lv2 #A2alternatingCurrent Playlist:    • Ch21 AC Circuits | CAIE 9702 A2 Physics   FM21 Paper Discussion Playlist:    • 9702 FM21 Papers CAIE Physics   Instagram Pocket Guide (  / etphysics  ) More Resources (https://9702-physics.blogspot.com/) Support us!
