Ammeter
Definition
An ammeter is an instrument used to measure the electric current flowing through a circuit. It tells us how many charges are passing through it per unit time.
Analogy
Think of an ammeter as traffic counter on a road. It counts the number of cars passing through a specific point in a given time, just like an ammeter measures the flow of charges (current) in a circuit.
