Question 1

Rectifier output is not a constant value due to the amount of ____ produced by different types of rectifiers.&#10;A) voltage&#10;B) current&#10;C) ripple&#10;D) pulse

Accepted Answer

Rectifiers produce ripple in the output due to the pulsating nature of the input AC waveform. The amount of ripple produced varies with different types of rectifiers, leading to an output that is not a constant value.

Question 2

Solid-state devices are made by combining P- and N-type materials together.

Accepted Answer

Solid-state devices, such as diodes and transistors, are made by combining P-type and N-type materials together to form a junction. This junction allows for the control and manipulation of electrons to create electronic signals and perform functions in electronic devices.

Question 3

The most common use of diodes in industry is to construct a rectifier.

Accepted Answer

Diodes are commonly used in industry to construct rectifiers, which convert AC voltage into DC voltage by allowing current to flow in only one direction.

Question 4

The simplest type of rectifier is known as the ____.&#10;A) full-wave rectifier&#10;B) half-wave rectifier&#10;C) bridge rectifier&#10;D) quarter-wave rectifier

Accepted Answer

The half-wave rectifier is the simplest type of rectifier as it only uses one diode to convert AC to DC by allowing only one half of the AC wave to pass through. The other options (full-wave rectifier, bridge rectifier, quarter-wave rectifier) all require multiple diodes and/or additional components to perform the rectification process.

Question 5

The diode is the simplest of all electronic devices.

Accepted Answer

The diode is indeed the simplest of all electronic devices, consisting of only two electrodes (an anode and a cathode) and allowing current to flow in only one direction.

Question 6

The diode can be tested with a(n) ____.&#10;A) ammeter&#10;B) voltmeter&#10;C) ohmmeter&#10;D) multimeter

Accepted Answer

An ohmmeter is the best choice for testing a diode as it can measure the resistance in both directions which will help determine if the diode is functioning properly or not. A voltmeter or ammeter can also be used but they are not as effective in detecting faults in a diode. A multimeter can perform all three tests (ohm, volt, amperage), making it a versatile tool for testing diodes.

Question 7

When the diode is to be connected in a circuit, there must be some means of ____ the anode and the cathode.&#10;A) identifying&#10;B) operating&#10;C) controlling&#10;D) connecting

Accepted Answer

Identifying the anode and cathode is essential for correct diode installation, as diodes allow current to flow in only one direction.

Question 8

The diode operates like an electric check valve in that it will permit current to flow through it in two directions.

Accepted Answer

The diode only allows current to flow through it in one direction, from its anode to its cathode. It acts as a one-way street for electric current.

Question 9

The PN junction is often referred to as the ____.&#10;A) triac&#10;B) transistor&#10;C) terminal&#10;D) diode

Accepted Answer

The PN junction is a type of semiconductor junction formed between a p-type and an n-type semiconductor material. This type of junction behaves like a one-way valve for electric current, allowing it to flow in only one direction, similar to a diode. Therefore, the PN junction is often referred to as a diode. The other choices, triac and transistor, are also semiconductor devices but they are not specific to the PN junction. Terminal is a generic term for a connection point in an electronic circuit.
