An example of "active" could refer to several things depending on the context. Here are a few examples in different areas:
1. **In grammar (active voice):**
*"The cat chased the mouse."*
In this sentence, the subject (the cat) is performing the action of chasing. This is active voice because the subject is doing something.
2. **In physics (active components):**
Active components are parts in an electrical circuit that can amplify or generate power, like transistors and operational amplifiers (op-amps). For example, a transistor is an active component because it controls the flow of electrical current.
3. **In physical activity:**
If someone is **active**, they are engaging in physical movement, like running, walking, or exercising.
4. **In general usage:**
A person who is always moving, engaged in activities, or involved in various projects can be described as being "active."
