How can we decide the direction of electric current ?

Define the rule used to identify the direction of induced current in an electric generator. How can we increase the amount of electric current produced in the electric generator? Mention the property of the current produced by AC generator. Mention an important advantage of this type of current.

The polarity of an electromagnet can be changed by changing the direction of electric current through the coil.

(A) : A galvanometer can be used as an ammeter and Voltmeter. (R) : A galvanometer cannot be used in electric circuit to detect the direction of electric current.

Write direction of electric current in electrolyte.
