TLE 9: BASIC Electronics

What is the main focus of electronics?

• Heat and light emission

• Emission and effects of electrons

• Motion of mechanical parts

• Chemical reactions

How does electronics differ from electricity?

• Electricity can only produce heat

• Electronics can manipulate the electrical current itself

• Electronics does not involve electric current

• Electricity transforms mechanical energy

What can an electric current be manipulated to carry?

• Water

• Sound, video, or data

• Air

• Mechanical force

Which statement describes Conventional Current flow?

• Current flows from negative to positive

• Current flows out of the positive terminal

• Current flows in a circular motion

• Current does not flow in a circuit

What is true about Electron Flow of current?

• Electrons flow out of the positive terminal

• Electrons flow out of the negative terminal

• Electrons do not move in a circuit

• Electrons flow in a random direction

What is the function of a resistor?

• It stores electrical charge

• It restricts the flow of current

• It generates electrical energy

• It amplifies signals

Which component is used to store an electric charge?

• Resistor

• Capacitor

• Switch

• Transistor

What does a switch do in an electronic circuit?

• Stores electrical charge

• Interrupts or diverts current

• Amplifies signals

• Restricts current flow

What is the function of a transistor?

• Stores charge

• Restricts current

• Regulates current or voltage flow

• Interrupts current

How does a diode function in a circuit?

• It allows current to flow easily in both directions

• It restricts current flow in both directions

• It allows current to flow in one direction

• It stores electrical charge
