What do you call a theoretical circuit used in analysis, that retains all of the electrical characteristics of a given circuit?

On an alternating-current appliance with a three-prong plug, on which lead should the power switch be connected?

In which of the following configurations do the capacitor(s) have the smallest individual voltages?

Consider an npn and a pnp transistor connected in series between the positive and negative terminals of a voltage supply. A signal is input to the base of each and output to ground from their collector-emitter connection. What is the common name for this configuration?

What standard circuit network often manifests as a "trim" potentiometer?

Consider a switch on a high-voltage circuit that is unsafe to operate manually. How might the switch be safely actuated?

How many diodes are required to build a full-wave rectifier that employs a center-tapped transformer?

The minimum root-mean-square magnitude of alternating currents that are likely to cause uncontrollable muscle contraction and heart fibrillation in a human are in what range?

On a printed circuit board that supports several different inductors in different circuits, are there any constraints to the layout of the inductors?

What is the term to describe a multivibrator circuit with two outputs, neither of which is stable in time?

Which power supply takes its power from more than one source?
