Nickel-chromium alloy wire and tungsten wire which is good?
The melting point of tungsten wire is higher than the melting point of nickel-chromium alloy wire, so we use tungsten wire as the bulb.
Nickel-chromium alloy wire resistivity than tungsten wire resistivity, so we usually use nickel-chromium alloy wire to do the resistor (set resistance, variable resistance).
See what you are doing! Filament is the high melting point with tungsten wire
