The circuit element whose purpose is to convert electrical energy into another form of energy is the battery resistor fuse ammeter

Answer : The correct option is, Resistor.

Explanation :

Battery : It is a type of device that contains one or more cells in which the chemical energy converted into electrical energy. The battery is used as a source of power.

Resistor : It is a device which resist's the flow of current in an electric circuit. When an electric current pass through a resistor it gets heated up due to the conversion of electrical energy into heat energy.

Fuse : It is a safety device which contains a strip of wire that breaks an electric current when the current increases to a safe level.

Ammeter : It is an electrical device in which measures the electric current in amperes.

Hence, the correct option is, Resistor.
