5 Questions
What is the primary characteristic of active components in a circuit?
They rely on an external power source to control current flow.
What is the main difference between direct current (DC) and alternating current (AC)?
The direction of electron flow (DC flows in one direction, AC flows in periodically reversing directions).
Which type of circuit contains components that are incapable of controlling current flow?
Passive circuits.
What type of current is generated by batteries, power supplies, and solar cells?
Direct current (DC).
What type of circuit is characterized by a contiguous signal?
Analog circuit.
Study Notes
Circuit Classification
- Active circuits contain components that rely on an external power source to control current flow.
- Passive circuits contain components that are incapable of controlling current flow.
Types of Circuits
- Analog circuits are characterized by a contiguous signal.
Current Types
- Direct Current (DC) flows in only one direction.
- Sources of DC include batteries, power supplies, thermocouples, solar cells, and dynamos.
- Alternating Current (AC) periodically reverses direction.
- Hydroelectric plants are a source of AC.
Learn about the basics of electronic circuits, including active and passive circuits, analog circuits, and the differences between direct current and alternating current.
