Genecon Parallel Bulb Base 4 Bulbs allows for convenient experiments measuring electric current and potential difference in a parallel circuit. The Genecon Parallel Bulb Base 4 Bulbs is a valuable tool for conducting experiments that require precise measurements of electric current and potential difference in a parallel circuit. This base for a parallel circuit contains four miniature bulb sockets and two terminals at each end, providing learners with a time-saving solution for their experiments. The base serves as a demonstration of energy conversion, electricity, and work concepts. The amount of electricity determines the number of miniature bulbs that light up. When all the bulbs are illuminated by Genecon, the handle's speed and torque will increase. Brand: Narika Current: 3.8V 300mA Included: 4 bulbs Dimensions: 180 x 80 x 25mm Product Code: SE.EM0275-13
