1

A diode to an electronic circuit is like a _______________ to a city?

67% Answer Correctly

one-way street

traffic light

highway

parking lot


Solution

A diode allows current to pass easily in one direction and blocks current in the other direction.


2

Direct current flows from the __________ terminal of the voltage source to the __________ terminal.

62% Answer Correctly

negative, positive

positive, positive

positive, negative

negative, negative


Solution

Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery.


3

What kind of diode allows current to flow in the opposite direction once a certain voltage threshold is reached?

50% Answer Correctly

light emitting diode

v-type diode

zener diode

standard diode


Solution

A diode allows current to pass easily in one direction and blocks current in the other direction. A zener diode is a diode which allows current to flow in one direction as normal and will also allow current flow in the reverse direction when the voltage is above a certain value. This value is called the breakdown voltage.


4

Which of the following is not a common type of battery?

41% Answer Correctly

dry cell

wet cell

deep-cycle

power-cycle


Solution

Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery. The three most common types of batteries are dry cell (used in small devices like TV remotes), wet cell (used for cars), and deep-cycle (storage batteries used primarily for backup and emergency power).


5

An amplifier is most similar in function to which of the following:

65% Answer Correctly

transistor

capacitor

step-down transformer

step-up transformer


Solution

An amplifier is a device that takes a small input signal and creates a larger output signal. This makes it most similar to a step-up transformer which takes a smaller input voltage and creates a larger output voltage.
