García Sánchez 1 2 3 4 5 6 7 8 Resistor: limits or controls the amount of electric current passing through the circuit. Transformer: increases or decreases the voltage of the electric current passing through the circuit. Bulb: gives out heat and light when the electric current passes. Switch: used to turn the electric current on and off Fuse: consists of a thin metal wire that melts to break the circuit if too much electric current passes through. Helps protect electrical applications. Cell (one) and battery (more than one cell): produce the electromotive force which pushes the electrons around the circuit. The long line is the positive terminal and the short line is the negative terminal. Ammeter: measures the rate of flow of the electric current passing through the circuit or part of the circuit. Voltmeter: measures the ability of the battery to push electrons through the circuit (voltage)
