The current in a 24-mH inductor is given by the waveform in the figure below. Find the waveform for the voltage across the inductor

Two capacitors give an equivalent capacitance of 9.00 pF when connected in parallel and an equivalent capacitance of 2.00 pF when connected in series. a.) What is the capacitance of each capacitor? b.) John was asked to design a capacitor in which small size and large capacitance were required. He said that he can achieve that by inserting a piece of paper between the plates. Do you agree with him? Why? Is there anything else that could be done to increase the capacitance?

A 39-H inductor is in a series circuit with a 12-V battery and a 25-Qresistor. A switch completing the circuit is closed. When the switch is closed, find the initial voltage difference across the resistor. Answer in Volts.

Describe in words how the charges behave on capacitors which are in a parallel circuit. How do the individual capacitor charges compare to the charge of the equivalent capacitor?
