25 cards
Card 1
Question: What are the two broad categories of electronic components?
Answer: Passive and active (or semiconductor) devices
Card 2
Question: What is a key characteristic of passive electronic components regarding power?
Answer: They do not require an external power source to operate and cannot amplify or generate power.
Card 3
Question: What is the primary function of passive electronic components?
Answer: They typically dissipate, store, or release energy.
Card 4
Question: Which electronic components are considered passive devices?
Answer: Resistors, capacitors, and inductors
Card 5
Question: What is a key characteristic of active electronic components regarding power?
Answer: They often require an external power source to function.
Card 6
Question: What functions can active electronic components perform?
Answer: Control electron flow, amplify signals, or switch currents
Card 7
Question: Which electronic components are primarily semiconductor devices and considered active?
Answer: Diodes and transistors
Card 8
Question: What is a capacitor?
Answer: A passive electronic component that stores electrical energy in an electric field.
Card 9
Question: How is a capacitor constructed?
Answer: It consists of two conductive plates separated by an insulating material called a dielectric.
Card 10
Question: What happens when voltage is applied across a capacitor's plates?
Answer: An electric charge accumulates on them, creating an electric field within the dielectric.
