which has a greater electrical resistance, a filament in a light bulb or a copper conducting wire.and how do you know this?
Jen or maria.... I gave you a number of sites to read on electical resistance. Also, I am sure you text book has some information that will be useful.
A higher resistance should generate more heat. Which do you think is hotter, the glowing filament in a light bulb or a copper wire?
DO NOT TRY TO TOUCH EITHER!
To determine which has a greater electrical resistance between a filament in a light bulb and a copper conducting wire, we need to understand the properties of both materials.
First, let's consider the filament in a light bulb. It is typically made of tungsten or a similar material. Filaments are intentionally designed to have high resistance to generate heat and light. This resistance is necessary to convert electrical energy into light energy.
On the other hand, copper is a highly conductive material commonly used in electrical wiring. Copper has low resistance, allowing it to efficiently carry electric current while minimizing energy loss in the form of heat.
Therefore, based on the fundamental properties of these materials, we can determine that the filament in a light bulb generally has a greater electrical resistance compared to a copper conducting wire.
If you want to verify this information, you can consult reference materials such as physics textbooks or reliable online sources that provide data on electrical resistance of different materials. Additionally, you can perform experiments with resistors made from tungsten (similar to light bulb filaments) and copper wires using a multimeter or an ohmmeter to measure their resistances.
