A resistor is an element that obstructs the flow of current in a circuit in accordance with

Three-phase alternating-current power is typically distributed on how many independent conductors?

Which model is generally used for transmission lines?

Which of these is a passive electronic component?

Which of these is an active electronic component?

Which of these is NOT a part of a regular DC power supply?

Two cross-coupled (the output of one gate serves as one of the other gate's inputs) NOR gates constitutes what type of digital circuit?

Consider a typical household AC circuit that is protected by both a circuit breaker and a ground-fault interruptor. A person accidentally shorts the hot lead to ground, drawing a lethal current of 100 mA. Which of the two safety devices will trip?

What is the typical low-voltage cutoff for a "high" signal in transistor-transistor logic (TTL)?

Of what safety device is this a description: A primary circuit that is magnetically coupled to a secondary circuit in which imbalance of hot and neutral current is measured?

Which model makes the simplifying assumption that all components in a circuit are ideal and all wires conduct perfectly?
