Can friction power a light bulb
WebIn a simple circuit such as a light bulb with a voltage applied to it, the resistance determines the current by Ohm’s law, so we can see that current as well as voltage must determine the power. Figure 19.20 On the left is a 25-W light bulb, and on the right is a 60-W light bulb. WebJan 10, 2024 · All you need to do is rub the fluorescent bulb with the plastic, fabric, fur, or balloon. Do not apply pressure. You need friction to make the project work; you don't need to press the material into the bulb. Don't expect the light to be as bright as it would be plugged into an outlet. It helps to turn off the lights to see the effect.

WebBut people can also have power that is measured in watts much like a light bulb or refrigerator. Power is calculated using a simple formula… Power = Energy/Time. The average human generates around 100 watts in an average day. Depending on the person's activity, weight, and metabolism, a person's power can be slightly higher or lower. WebFriction - Friction Ladder; Hoberman Sphere; Force Plate; Angular Momentum - Irregular Top; ... which by Lenz's Law induces a current within the coil.

WebFeb 21, 2024 · $\begingroup$ Light bulbs do NOT have "a resistance". The resistance depends highly on filament temperature, hence on current. You cannot just measure the bulb with a multimeter to be e.g. 60.0 ohm, and write that 60.0 ohm in the diagrams. ... the bulb with the most resistance will not only get more power than the other bulbs, but get … WebViewed 11k times. 1. I'm studying a lightbulb and its variable resistance, given by the expression: R ( T) = R o [ 1 + α ( T − T 0)], where R 0 is the resistance of the lamp at T 0. In this case, R is not given by Ohm's law ( V = R i ). So, which expression can I use to calculate the power consumed by a lightbulb?
