(Fill in the blank)

Electronics is a field of science in which we study about electric ______ generated due to the movement of electric charges that flow in _____ that store and handle information, and how to control these currents.

a)

curves, the ground

b)

electrons, thin air

c)

currents, circuits

d)

cycles, outer space

2.

Which of the following is responsible for leaving the atom, only to be replace, and creates the movement we refer to as electricity?

a)

Proton

b)

Electron

c)

Neutron

d)

Nuclus

3.

In the water pump analogy, what happens as the water passes through the system?

a)

The water is pushed out of the system and creates a leak

b)

The water pump acts like a battery, which forces out water in both directions.

c)

The water experiences resistance as it passes through the smaller pipe.

d)

The current is disrupted by the resistance and the water stops flowing.

4.

Which of the following is a common conductor and insulator combination used for electric current?

a)

Steel and Plastic

b)

Water and Humans

c)

Silver and Wood

d)

Copper and Rubber

5.

Conventional Current flows from

a)

Positive to Neutral

b)

Positive to Negative

c)

Positive to Nucleus

d)

Positively Counter Clockwise

6.

Which of the following is true about reverse polarity when applied to the following circuit components:

a)

Some components, like diodes (LEDs are diodes), do not allow for revers polarity

b)

All components are capable of reverse polarity.

c)

Resistors will blow up if you reverse polarity.

d)

Polarity is the opposite of the sun.

7.

Which of the following is true as it relates to Voltage, which is nothing but a type of force that a power source creates at its two ends.

a)

This force makes the charge flow around the circuit.

b)

This force is unnatural, and made exclusively by humans, as electricity is not seen in nature

c)

Voltage is like a car driving on a freeway.

d)

Voltage is always safe as long as you use an insulator.

8.

Which of the following are NOT true about batteries (there may be multiple correct responses).

a)

The larger the battery, the larger the voltage.

b)

Batteries come in various sizes.

c)

Batteries fluctuate in voltage even when not in use.

d)

Batteries were first designed by Elon Musk.

9.

What are the essentials of an electronic circuit? (There may be more than one answer)

a)

Conductors - Like Wires

b)

Load - Like and LED

c)

Power Source - Like a Battery

d)

Capacitor - Like a Fuse

10.

(There may be more than one answer)

Resistors are important because...

a)

They prevent components from being damaged.

b)

They are capable of dropping the voltage of a circuit.

c)

They make the circuit more powerful.

d)

They eliminate the need for code.
