(c) What is the net energy? 2 C 1 v s v o R 2 R 1 R 3 R 3 R 2 R 2 5. (a) Find the transfer function of the above circuit. (b) Calculate the output signal when the circuit is excited by a periodic square wave signal input signal shown below. The period of the signal is 1 μ s and the rise and fall times are 10% of the period. C 1 = 9 . 7nF, R 1 = 15kΩ, R 2 = 130kΩ, and R 3 = 570Ω. v ( t ) 1V t ( μ s) 1 6. Suppose you want to store enough energy in a capacitor so that you can run your 1kW microwave oven for 30 minutes. How big is the required capacitance if you can charge it up to 100V? What are the capacitor dimensions if you build it as a parallel plate square capacitor with a dielectric with relative permittivity ǫ r = 10 with a thickness of 1 μ m. 3...
