Question 1

Long runs of wire have the effect of reducing resistance to the lines.

Accepted Answer

Long runs of wire actually increase resistance, as resistance is directly proportional to the length of the wire.

Question 2

A current generator can be constructed using either a field effect transistor or a junction transistor.

Accepted Answer

Both field effect transistors (FETs) and bipolar junction transistors (BJTs) can be used in the design of current generators due to their ability to control current flow.

Question 3

A ____ circuit is used to produce an output that is sensitive to an amount of current flow as opposed to some amount of voltage.&#10;A) current differentiator&#10;B) current converter&#10;C) current generator&#10;D) current diverter

Accepted Answer

A current generator is used to produce an output that is sensitive to an amount of current flow as opposed to some amount of voltage.

Question 4

Many digital ohmmeters measure the value of a resistor by passing a known amount of current through it and then measuring the voltage drop across the resistor.

Accepted Answer

Digital ohmmeters typically work by applying a known small current through the resistor to measure the voltage drop across it. According to Ohm's Law (V = IR), the resistance can then be calculated.

Question 5

A pnp junction transistor cannot be used to construct a current generator.

Accepted Answer

A PNP junction transistor can be used to construct a current generator, as it can operate in active mode to provide a stable current source by controlling the base-emitter voltage.

Question 6

Almost any range of resistance can be measured through a digital ohmmeter by using the proper amount of current and the correct ____.&#10;A) correction factor&#10;B) loss factor&#10;C) inversion factor&#10;D) multiplication factor

Accepted Answer

The correct term is "multiplication factor." In the context of measuring resistance with a digital ohmmeter, the multiplication factor is used to adjust the measurement range to accurately measure different levels of resistance by applying the appropriate amount of current.

Question 7

The formula ____ can be used to calculate the value in of ohms that a resistor can have.&#10;A) R = I / E&#10;B) R = E / I&#10;C) R = E * I&#10;D) R = C / E

Accepted Answer

The correct formula for calculating the resistance (R) in ohms of a resistor is R = E / I, where E is the voltage (in volts) and I is the current (in amperes). This formula is derived from Ohm's Law.

Question 8

____ are used to sense temperature, pressure, humidity, etc.&#10;A) Analog sensing devices&#10;B) Analog translation devices&#10;C) Analog converters&#10;D) Analog inverters

Accepted Answer

Analog sensing devices are specifically designed to measure physical conditions such as temperature, pressure, and humidity, converting these physical quantities into analog electrical signals.

Question 9

Analog sensing devices are sensors that are designed to operate between some range of settings.

Accepted Answer

Analog sensing devices are designed to operate over a continuous range of values, allowing them to measure parameters such as temperature, pressure, or light intensity within a specific range, rather than just providing on/off or discrete states.

Question 10

A ____ can be used to maintain a constant voltage between a base and emitter.&#10;A) JFET diode&#10;B) photo diode&#10;C) zener diode&#10;D) Gunn diode

Accepted Answer

A Zener diode is specifically designed to operate in the reverse breakdown region, allowing it to maintain a constant voltage across its terminals, making it ideal for voltage regulation purposes, such as maintaining a constant voltage between a base and emitter in a circuit.
