True or False? A variable inductor can only be constructed with the use of superconductors.

What is the open-loop gain of an ideal op-amp?

How is the charge stored in a capacitor related to the voltage applied to the capacitor?

Which components form a Darlington pair?

A diplexer has how many output connections?

True or False: A photodiode connected in photoconductive mode has better response time than that connected in photovoltaic mode.

Which of these is used in the graphical analysis of non-linear circuits?

In an N-channel depletion mode FET, the negative gate-source voltage at which the depletion region expands to completely close the conductive channel is called:

Compare the currents of these two circuits: (1) a battery connected in parallel with four identical parallel resistors and (2) the same battery connected to only three of the identical parallel resistors.

In a series RLC alternating-current circuit, which element will dominate the reactance of the circuit when the frequency is below resonance?

True or False? A transformer requires a ferrite core.
