Solution
Resistor function is to reduce the flow of electric current.
Battery function is store energy . it shows the amount of electric charges a battery can hold (capacity)
Voltmeter function is to measure potential difference (i.e. voltage) between two points.
Ammeter function is used to measure electric current.
A Rheostat is used to provide variable resistance in the circuit. Its resistance can be varied as per the requirement.The required resistance may be low or high.
Galvanometer is an device used to measure current in a circuit. It is used to perform various activities like performing activity to test presence of current while magnet is in motion.
