What is the role of an ammeter in a circuit?

An ammeter is specifically designed to measure the flow of electric current in a circuit. It is connected in series with the circuit components, allowing it to accurately gauge the amount of current passing through a specific point in the circuit. The unit of measurement for current is amperes, hence the name "ammeter."

This instrument helps in monitoring and diagnosing circuit performance and is crucial for ensuring that components are functioning within their specified current ratings. When an ammeter is inserted into the circuit, it can provide valuable readings that help engineers and technicians understand the operational characteristics of electrical systems, making it an essential tool in both theory and practice within electrical engineering.
