Testing Electronic Components (TEC) Quiz

What is the purpose of a job order in a manufacturing environment?

• To list the total amount of hours worked

• To signal the start of a manufacturing process

• To provide warranty information

• To dispatch orders received from outside the organization

What is the function of a light dependent resistor (LDR) in electronic circuit designs?

• To detect the presence or level of light

• To amplify current

• To maintain a constant current flow

• To allow current to pass in only one direction

What is/are the purpose/s of an owner's manual for consumer products? [check all that applies]

• To provide troubleshooting instructions and service locations

• To provide safety instructions and assembly guidelines

• To list included and optional accessories

• To give information about power requirements and energy consumption

What is the main function of a variable resistor, commonly called a potentiometer?

• To maintain a constant current flow despite voltage fluctuations

• To emit light when current flows through it

• To adjust the resistance from virtually zero ohms to a maximum value

• To allow current to flow in only one direction

What is the main characteristic of non-polarized capacitors?

• Their capacitance may be intentionally and repeatedly changed mechanically

• They allow current to flow 'backwards' when a certain reverse voltage is reached

• They can be randomly inserted into the circuit and will not leak

• They have specific positive and negative polarities

What is the main function of a Schottky diode?

• To have a low forward voltage drop and a very fast switching action

• To allow current to pass in only one direction

• To emit light when current flows through it

• To maintain a constant current flow despite voltage fluctuations

What is the main characteristic of a tunnel diode?

• It is a two-lead semiconductor that allows current to pass in only one direction

• It is a semiconductor device commonly used for amplification

• It has effectively 'negative resistance' due to the quantum mechanical effect called tunneling

• It is a special type of diode designed to reliably allow current to flow 'backwards'

What is the main function of a bipolar transistor?

• To detect the presence or level of light

• To adjust the resistance from virtually zero ohms to a maximum value

• To emit light when current flows through it

• To amplify analog or digital signals and switch DC or function as an oscillator

What is the main characteristic of a varactor diode?

• Its internal capacitance varies with the variation of the reverse voltage

• It is a semiconductor device commonly used for amplification

• It is a special type of diode designed to reliably allow current to flow 'backwards'

• It is a two-lead semiconductor that allows current to pass in only one direction

A resistor whose resistance is dependent on temperature

• Thermistor

• Variable resistor

• Fixed resistors 

• Not in the list
