a galvanometer
What device produces light by running an electric current through a gas?
Electric discharge
What m-word is defined as a device that changes sounds into electric current?
microphone
Electric current is measured using what device?
ammeter, which is understood as an amp meter
A device that produces an electric current by rotating a loop of wire in a magnetic field?
That's how every electric generator works.
What is the definition of AC generator?
An electric device that produces an electric current that reverses direction many times per second. Also called a synchronous generator.
What is the purpose of a rectifier?
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction.
What is the Simplest protective device for an electric current?
A fuse is the simplest protective device for over current in an electric circuit.
What does the retifier on gators do?
Assuming you mean "rectifier", a rectifier is an electrical device that converts AC, which periodically reverses direction, to DC, which flows in only one direction.
What device uses motion in an electric field to produce an electric current?
electric genarator
What is a device that uses electric current to represent coded information?
An electronic device uses electric to represent coded information. Variations in the current are converted to codes used by the electronic device.
What does LED stand for in relation to light?
LED = Light-Emitting Diode This is a semiconductor diode that emits light when an electric current is applied in the forward direction of the device.
What is the device that measures the strength of an electric current?
ammeter
What is a device that measures the strength of an electric current?
