Power Analysis Learning Goal: This problem aims to help you practice calculating power dissipation in di?'erent circuit elements. It will also give you insights into how power is conserved in a circuit. (a) Find the expressions of power dissipated by each element in the circuit above, Remember to label voltage-current pairs using passive sign convention. 03) Use R = 5kg, V, = 5V, and I = 5mA. Calculate the power dissipated by the voltage source (Pig), the current source (P1), and the resistor (H2). (c) Once again, let R = SkQ, V,» = 5V. What does the value I of the current source have to be such that the current source dissipates 40mW? Note that it is possible for a current source to dissipate power, i.e. under passive sign convention, P; = 40mW. For this value of I, compute Pv, , P1, and PR as well, As an aside: [f the current source were delivering power it would have been P1 = -40mW, under passive sign convention, but this is NOT what the question is asking about.
