Why does the filament of a lightbulb glow while the connecting wires do not?
Step 1 of 3
Solution 20E The filament of a lightbulb is thin and so it experiences a very high resistance. This is in accordance with the relation R 1/A , R is resistance and A is the cross-section. The filament has a low area of cross-section and hence the resistance R is very high. This high resistance causes the electrons in the filament to collide more with the filament atoms during the passage of...
