Unformatted text preview: Problem 5. Using Phasor to solve AC Circuits .For the circuit given below, i s1 (t) = 2cos(ωt) A, and Vs 2 (t) = 300sin(ωt) V, where frequency = 1kHz. a. Convert this problem to a phasor problem. Label all the currents and voltages and specify reference directions. Write down the KCL and KVL equations. (work with the phasors). b. Solve the equations and find the phasors corresponding to the voltages across R 1 and C 1 . c. Convert the phasor voltages in part b. to time dependent voltages, i.e. find v(t) across R 1 and C 1 . Problem 6. Learning how to simplify AC circuits. Also, understanding average power. .For the circuit given below, Vs(t) = 100sin(300πt  3π/4) V. a. Use phasors to solve for the voltage across R, recognize elements in parallel and simplify them. Convert the phasor to time dependent voltage. b. What is the average power dissipated in the inductor, resistor and capacitor....
