a galvanometer
No, a galvanometer does not have polarity. It is a device used to detect and measure small electric currents. The deflection of the needle in a galvanometer indicates the presence and direction of the current but not the polarity.
A microphone is the device that changes sounds into electric current.
An electroscope is a device that can detect the presence of electric charge. It is typically used to determine whether an object is charged positively or negatively. When an electroscope detects an electric charge, the metal leaves inside the device will either repel or attract each other, indicating the presence of charge.
ammeter, which is understood as an amp meter
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.

A fuse is the simplest protective device for over current in an electric circuit.
0.78 amps is a measure of electric current. It represents the flow of electric charge per unit of time. This value indicates how much current is passing through a circuit or device at a given time.

ammeter, which is understood as an amp meter
An electroscope is a device that can detect the presence of electric charge, including electrons. When a charged object is brought close to the electroscope, the electrons on the device are repelled or attracted, causing the leaves to diverge. This divergence indicates the presence of electrons on the object being tested.
electric genarator
An electronic device uses electric to represent coded information. Variations in the current are converted to codes used by the electronic device.
ammeter
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.
