Simple electrical circuit as part of a classroom demonstration. The circuit consists of three cells (batteries,across top),which are powering the electric motor (bottom right). A resistor (black,left of motor) is being used to reduce the amount of electric current to a safe level,as shown by the digital ammeter (lower left). Crocodile clips and wires connect these components to complete the circuit. An electric motor converts electrical energy into motion. This is a 9-volt Lego motor | |
