Textbook Question
Chapter 28, Problem 65P
A “black box” has two input connections and two output connections. With a 12-V rms, 60-Hz sine wave across the inputs, the output is a 6.0-V, 60-Hz sine wave leading the input voltage by 45°. Design a circuit that could be in the “black box.”

. A capacitor of capacitance 80 µF is giving supply voltage V= 10 Sin ωt to one end of an oscillator. How can you evaluate the peak voltage of the circuit, if ω is changing from 10 to 100 rad/sec? Evaluate the difference between the peak values during the change of ω from 10 to 100 rad/sec. The capacitor acts an open circuit here. Justify your answer?
A high‑voltage discharge tube is often used to study atomic spectra. The tubes require a large voltage across their terminals to operate. To get the large voltage, a step‑up transformer is connected to a line voltage (120 V rms) and is designed to provide 3100 V rms to the discharge tube and to dissipate 90.0 W.
What is the ratio of the number of turns in the secondary to the number of turns in the primary, Ns/Np?
What are the rms currents ip,rms andis,rms in the primary and secondary coils, respectively, of the transformer?
A 2.44 kΩ resistor is connected to an AC voltage source with an rms voltage of 230 V.
