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?

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

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?

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?

Which of the following combinations of gates could be used to realize the XOR function?

For which values of inputs A and B would a NAND gate and an XOR gate NOT have the same output?

Which of these is a passive electronic component?

Which model is generally used for transmission lines?

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

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

In an 8-bit encoding, how many different values can be represented?
