Technician A says that fiber optic technology has the potential to replace copper wires as electrical conductors. Technician B says that fiber optics have the potential to be used more extensively as communication buses in vehicles. Who is correct?

Which of the following describes a closed circuit?

What type of transistor is often used as a driver switch in a circuit such as a truck ECM injector driver unit?

A diode that tests showing high resistance in both directions is:

When a diode is in reverse bias, what does it do?

A circuit in which there is only one path for current flow is known as:

Which of the following is true of a lead acid battery?

Which of the following describes an open circuit?

Using the binary system, if 0 = 0000 0000 and 1= 0000 0001, what does 0000 0100 equal?

What electrical principle is used to make a diesel engine exhaust system pyrometer function?

What is an atom with a deficit of electrons known as?

A diode that is designed to block reverse bias current but only up to a specified voltage is known as?

What happens to current flow if an electrical circuit is shorted?

Technician A says that piezoelectric effect is reversible. Technician B says that piezo actuators respond more slowly to inputs because they are required to build a magnetic field before a mechanical response results. Who is correct?
