Silver instead of copper wire in electric generators?

This means that silver has slightly lower resistance, but the difference is negligible. However, using silver wire instead of copper wire can reduce resistance losses, which can result in more efficient generators. The switch from silver to copper wire may also affect the voltage and current, as copper has a slightly higher resistivity. Additionally, using silver wire can increase transformer losses, which can impact the overall efficiency of the system. During World War II, silver was used as a substitute for copper in some U.S. wartime projects due to the high demand for brass for shell casings. It was also used in military transmitters for RF coils.

I'm wondering if it make much difference if they used silver instead of copper wire in electric generators? Also, how does switching from silver to copper wire affect the voltage and current, or does it just create some resistance?

It reduces resistance losses , but probably increases (stolen) transformer losses

I think that during World War II, silver was substituted for copper in some U. S. wartime projects because brass was being used for shell casings. I am told also that solid silver wire was being used in the RF coils in military transmitters. See for example

Not much. The resistivity of silver is 1.6E-8 ohm-m, whereas that of copper is 1.7E-8
 

1. What is the difference between silver and copper wire in electric generators?

The main difference between silver and copper wire in electric generators is their conductivity. Silver is a better conductor of electricity than copper, meaning it allows electricity to flow more easily through it. This makes silver wire more efficient for generating electricity.

2. Why is silver not used instead of copper in all electric generators?

While silver is a better conductor than copper, it is also significantly more expensive. In fact, silver is one of the most expensive metals in the world. Therefore, it is not economically feasible to use silver in all electric generators, especially for large-scale power generation.

3. Can silver wire be used in place of copper wire in existing electric generators?

Yes, silver wire can be used in place of copper wire in existing electric generators. However, it may require some modifications to the generator's design and may not be cost-effective in the long run.

4. Is silver wire more durable than copper wire in electric generators?

No, silver wire is not more durable than copper wire in electric generators. In fact, silver is a softer metal than copper, making it more susceptible to damage and wear over time. This can lead to a shorter lifespan for silver wire in electric generators.

5. Are there any environmental benefits to using silver instead of copper in electric generators?

Yes, there are some potential environmental benefits to using silver instead of copper in electric generators. Silver is a more efficient conductor, meaning less energy is lost as heat during electricity generation. This can result in lower carbon emissions and a reduced impact on the environment.
