Understanding Electric Current
Electric current is the flow of electric charge, typically measured in amperes (A). To quantify this flow, specific devices are used in electrical circuits.
What is an Ammeter?
- An ammeter is a specialized instrument designed to measure electric current in a circuit.
- It is connected in series with the circuit, allowing the current to pass through it for accurate measurement.
- The reading on an ammeter indicates the amount of current flowing through the circuit at that given moment.
Why Not a Voltmeter?
- A voltmeter measures voltage, or electrical potential difference, across two points in a circuit, not the current itself.
- It is connected in parallel, which is different from how an ammeter is connected.
Role of Electroscope
- An electroscope is an instrument used to detect the presence of electric charge, but it does not measure current.
- It helps indicate whether an object is charged or not, but lacks the capability to quantify current flow.
Conclusion
- In summary, the correct answer to the question of which device measures electric current is indeed an ammeter (option B).
- Understanding these instruments is essential for studying electricity and its applications in various fields.
