(DC).
Converter - answer An apparatus that changes direct current (DC) to (AC) alternating
current.
Transformer - answer Used to change the voltage of a current.
Rheostat - answer Instrument used to regulate the strength of a current.
Condenser - answer An apparatus used for collecting charges of electricity in which the
