An electronic device uses electric to represent coded information. Variations in the current are converted to codes used by the electronic device.
A fuse is the simplest protective device for over current in an electric circuit.
An ammeter is a device that indicates the presence of an electric current by measuring the flow of electric charges through a circuit.
A microphone is the device that changes sounds into electric current.

An ammeter is a device that measures the strength of an electric current. It is usually connected in series with the circuit where the current is to be measured and provides a reading in units of amperes.
A galvanometer is a device that uses an electromagnet to measure electric current. It works by converting the current passing through it into a proportional mechanical deflection of a pointer on a scale.
An electrometer is a device that detects electric charges by measuring the voltage or current associated with the charges.
When an electric device is connected to a battery, an electric current is produced due to the difference in potential between the positive and negative terminals of the battery. This potential difference, also known as voltage, creates an electrical force that pushes the flow of electric charge (current) through the circuit and powers the device.
