This useful unit includes four low voltage lamp holders connected in parallel and mounted on BES type base. Individual switches control each lamp, allowing all, some, or none of the lamps to be lit. Four colour-coded 4 mm 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. Suggested uses: • Use 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 simple circuit. • Simple to use and quick to set up, as individual components do not need to be connected together to make circuit.
