A Wheatstone bridge is used as a variable resistance sensor.

The different names for the legs of a transistor are the emitter, base, and collector.

The instrument panel warning light is called a DTC.

An electronic device that stores and processes data is a(n) ____________________.

Which of the following does NOT use a magnetic pulse generator [PM generator]?

A CAN [controller area network] bus is a low-speed data bus.

Describe the two ways a microprocessor works with memory.

Identify some common voltage-generating devices (sensors) in automobiles.

When disconnecting and connecting electronic components, the ignition switch should be turned off.

Under what circumstances should a computer be reflashed?

Technician A says some types of voltage sensors provide input to the computer by modifying or controlling a constant, predetermined voltage signal. Technician B says some types of voltage sensors provide a voltage generating signal. Who is correct?

Technician A says when positive voltage is applied to the base of an NPN transistor, the transistor is turned on. Technician B says when an NPN transistor is turned on, current flows through the collector and emitter of the transistor. Who is correct?

Which of the following is a semiconductor?

Variable capacitors are called ____________________.

Terminating ____________________ are connected in parallel across the ends of the main CAN bus wires to eliminate potential voltage spikes or noise on the data bus.

OBDII technology is being discussed. Technician A says the OBDII system has the ability to store a freeze frame [snapshot] of the operating conditions that existed when the fault occurred. Technician B says vehicle identification must be transmitted automatically to the scan tool. Who is correct?
