a) The house circuit diagram is shown in the figure below, where ⨷ represents a lightbulb of resistance r' and Reff = 2R. Use Kirchoff’s rules to find the loop currents in the following circuit, in terms of ε, R, and r'. b) Let  ε = 20 V and R = 2Ω. If you want the lightbulb with resistance r' to dissipate power 50W, what should r' be?

For a certain power shpply, the no load and full load voltage are 22 V and 18 V respectively. What will be the load regulation?
