Question

conventional incandescent light bulbs work by sending electric currents through what type of material? non - resistant resistant

Explanation:

Brief Explanations

Conventional incandescent light bulbs operate by passing electric current through a resistant material. When current flows through a resistant material, electrical energy is converted into heat (due to the resistance opposing the flow of electrons). As the resistant filament (usually tungsten in incandescent bulbs) gets heated to a high temperature (around 2500 - 3000 K), it starts to glow and emit light (incandescence). If the material were non - resistant, there would be very little heat generated (as per \(P = I^{2}R\), where \(P\) is power, \(I\) is current, and \(R\) is resistance. If \(R\approx0\), then \(P\approx0\)), and thus no significant light emission from the incandescence process.

Answer:

Resistant
