Exam 3: Electrical and Electronic Componentsbasic Electrical Troubleshooting and Service

What is a complex circuit of many electrical devices such as transistors, diodes and logic gates called?

If a diode is ____, there will be current flow.

What device or devices use a low current input to control a high current output?

Technician A s ays a shorted circuit can generate excessive heat. Technician B says a shorted circuit will cause the circuit protection device to open. Who is correct?

Technician A says if a fuse blows as soon as it is installed, a short to ground is indicated. Technician B says the component will not turn off if the short to ground is on the ground side of the load component but before a grounding switch. Who is correct?

What does a switch control?

What solid state electronic device only requires a trigger pulse to its gate to become conductive?

Name the figure below and describe how it works.

The circuit breaker that protects a power window circuit opens whenever the window is lowered. Technician A says the internal resistance of the motor is too high. Technician B says the window regulator may be sticking. Who is correct?

Direction of current flow through a diode can be identified by a band around the cathode end.

A diode that allows current flow in both directions is ____.

Some automotive electrical systems use a capacitor or condenser to ____ electrical charges.

The trigger selection tells the lab scope when to begine to display a waveform.

Which of the following is true about a clamping diode?

The load current flowing through a transistor passes through the emitter and the base circuit.

What is a three-layer semiconductor that is commonly used as a very fast switching device?

Whenever the brake pedal is pressed the left-rear and right-rear taillights, and the left rear and the right-rear brake light of a vehicle illuminate dimly. Technician A says the brake lights may have a poor ground connection. Technician B says the brake light switch may have excessive resistance. Who is correct?

The term ____ means a circle and is the path of electron flow consisting of the voltage source, conductors, load component, and return path to the voltage source.

Technician A says a Zener diode is an excellent component for regulating voltage. Technician B says when a circuit is opened suddenly to a large load, such as a coil, installing a clamping diode provides a bypass for the electrons. Who is correct?

What will a Zener diode do at breakdown voltage?
