resistance in the de circuit of Figure QA1(a) given that: 8-120 R-39-602-6V and-12v R₁ + Type your solution here: R₂ Figure QA1(a) is given by The current through a pure capacitor of " 1000 pF 1-28.28cos(314), Derive a similar expression for the voltage across the capacitor and comment on your answer. Type your solution here: c) Refer to the circuit in Figure QA1(c). Use Microsoft Excel, or any similar software, to plot the variation of the output voltage with Type your answer here: And include your Plot. variation in R, over a suitable range. Justify calling this circuit a potential divider. Making any reasonable assumptions and modifications, explain how this circuit may be used as a darkness detector which can turn a mains-powered lamp automatically during darkness. Figure QA1(c).
