Do light bulbs have resistances circuits
WebLight Bulbs ÎA three-way light bulb contains two filaments that can be connected to the 120 V either individually or in parallel. A three-way light bulb can produce 50 W, 100 W or 150 W, at the usual household voltage of 120 V. What are the resistances of the filaments that can give the three wattages quoted above? Use P = V2/R ¾R WebYou may want to experiment with the sim again, keeping in mind that light bulbs are just resistors that glow.). Because there is only one way for the energy to get through,the current is the same current. The resistances all add together to make a …
