Web7 de dez. de 2012 · Dec 7, 2012 at 22:18. 2.4V bulb's resistance is 24Ohms, 1.5V's is 21Ohm. So if you will replace half of the bulbs with 2.4V ones — resistance of one segment will increase for 24Ohm. You can compensate this increase by shortening one bulb in segment. Just insert a piece of foil in the socket isntead of a bulb. Web14 de set. de 2010 · The incorrect story is that the electrons move happily through the low resistance wires but when they come to the bulb filament they find it difficult to squeeze through and all the jostling transfers energy to the filament, which we experience as heat and light. The higher the resistance, the more jostling and the brighter the bulb. fisherman characteristics https://phillybassdent.com
