What is the difference between active and passive components of an electric circuit?
Understand the Problem
The question asks to differentiate between active and passive components in an electrical circuit. Active components can introduce energy into a circuit, while passive components cannot. We will define and provide examples of each to highlight their differences.
Answer
Active components require external power and inject power into a circuit, whereas passive components don't require external power and cannot supply power.
Active components need an external power source to operate and can inject power into a circuit. Passive components do not require an external power source and cannot supply energy to a circuit; they only store or dissipate it.
Answer for screen readers
Active components need an external power source to operate and can inject power into a circuit. Passive components do not require an external power source and cannot supply energy to a circuit; they only store or dissipate it.
More Information
Examples of active components are transistors, vacuum tubes, and integrated circuits. Examples of passive components are resistors, capacitors, and inductors.
Tips
A common mistake is to think that all semiconductor devices are active. Some, like diodes, are passive.
