This useful unit includes four low voltage lamp holders connected in parallel and mounted on a BES type base. Individual switches control each lamp, allowing all, some, or none of the lamps to be lit. Four colour-coded 4mm sockets can be used to link multiple sets together or to connect a power supply and Voltage and Current sensors or meters.
Unit comprises: 4 On/Off toggle switches; 4 x 4 mm sockets; 4 lamp holders - supplied without bulbs, which are available separately.
• Use a hand powered generator (EN98100) to feel the increase in power and energy needed to successively light more lamps.
• Use with a battery or power supply to study the relationship between voltage, current and resistance.
• Useful for studying power, efficiency, and Ohm's law in a simple circuit.
• Simple to use and quick to set up, as individual components do not need to be connected together to make a circuit.
