Basics of Electronics

(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.

• curves, the ground

• electrons, thin air

• currents, circuits

• cycles, outer space

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

• Proton

• Electron

• Neutron

• Nuclus

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

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

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

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

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

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

• Steel and Plastic

• Water and Humans

• Silver and Wood

• Copper and Rubber

Conventional Current flows from

• Positive to Neutral

• Positive to Negative

• Positive to Nucleus

• Positively Counter Clockwise

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

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

• All components are capable of reverse polarity.

• Resistors will blow up if you reverse polarity.

• Polarity is the opposite of the sun.

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.

• This force makes the charge flow around the circuit.

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

• Voltage is like a car driving on a freeway.

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

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

• The larger the battery, the larger the voltage.

• Batteries come in various sizes.

• Batteries fluctuate in voltage even when not in use.

• Batteries were first designed by Elon Musk.

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

• Conductors - Like Wires

• Load - Like and LED

• Power Source - Like a Battery

• Capacitor - Like a Fuse

(There may be more than one answer)

Resistors are important because...

• They prevent components from being damaged.

• They are capable of dropping the voltage of a circuit.

• They make the circuit more powerful.

• They eliminate the need for code.
