An LED typically requires a series resistor to limit the current flow through the LED.

Technician A says that the stripe on a diode indicates the cathode end of the diode. Technician B says that the arrow on the schematic symbol for a diode indicates the direction of conventional current flow to forward-bias the diode. Who is correct?

The three terminals of a bipolar transistor are the emitter, the base, and the _______?

A "_____ bond describes the sharing of electrons between atoms.

Which of the following is a true statement?

Resistors are used for three main purposes in an electrical circuit. Resistors limit the current flow through a circuit, divide voltage, and _____?

A technician is testing a diode using a DMM in the diode test mode. She measures 0.7V when the diode is forward biased and the DMM indicates OL when the diode is reverse biased. What do these test results indicate?

Resistors are typically made from what material?

Technician A says that a zener diode emits visible light. Technician B says that a forward-biased diode describes a diode that is blocking the flow of electric current. Who is correct?

A bipolar transistor is a current-controlled device and a FET is a voltage-controlled device.

A wiring schematic indicates a diode is connected in parallel with an A/C clutch coil. Such a diode would likely be used as a suppression device.

Electronic components will typically recover from damage caused by improper troubleshooting techniques after disconnecting and reconnecting electric power to the device.

A technician measures approximately 0.7V across a diode in a 12V electric circuit. This indicates the diode is reverse biased.

The terminals of a zener diode include the anode, the cathode, and _____.

Rectifier diodes permit electric current to flow in one direction and block current flow in the opposite direction.

The addition of impurities to silicon to form a semiconductor is called doping.

Technician A says that a low-side driver provides a path to ground. Technician B says that a high-side driver provides a positive voltage. Who is correct?

Technician A says that a 1k ohm 2-watt resistor and a 1k ohm 1/2 watt resistor both have the same value of resistance. Technician B says that a potentiometer has two electrical terminals. Who is correct?
