Bronze, an alloy primarily composed of copper and tin, does conduct electricity, but not as efficiently as some other metals like copper, silver, and gold. The electrical conductivity of a material is determined by the number of free electrons available to carry an electric current. In pure metals like copper, there are many free electrons, … Read more
Fusion, the process that powers the sun and other stars, has the potential to generate electricity without carbon emissions, long-lasting nuclear waste, or risk of meltdowns. In a fusion reaction, two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process. The most commonly studied fusion reaction involves deuterium and tritium, … Read more
Summary Electric field lines are always perpendicular to equipotential surfaces. This is because the electric field is the gradient of the electric potential, and the gradient is always perpendicular to the level surfaces of a function. In the context of electric fields, the level surfaces are the equipotential surfaces, and the gradient is the electric … Read more
