How Does Voltage Affect Current Through a Filament Lamp? Equipment: * Power Supply. (Ranging from 0V to 6V). * Variable Resistor. * Ammeter. * Voltmeter. * 6V Filament Lamp. * 7 Wires. Definitions: Ammeter - This is a device that measures the current of electrons in Amps. It has to be placed in Series on the circuit. Voltmeter - This is a device for measuring the potential difference of the electrons in the circuit. They are measured in Volts. It is placed in Parallel. Variable Resistor - This acts in the same way as a normal resistor, to resist the current, but this one can have a variable (changeable) resistance. In this particular circuit, it is in Parallel Circuit Diagram: Plan: * To draw a circuit diagram. * To make a prediction of what might happen during the experiment and what the results may be like, and use previous knowledge or science knowledge to explain the prediction. Also to predict what...
