Electric Resistance Resistance – Electric

Text in the illustration

resistance of light bulb filament is high so a lot of heat and light are produced as the electricity forces its way through
resistance along circuit wire is quite low
the light bulb is a resistor

Generated explanation

The illustration shows an illuminated incandescent light bulb connected to circuit wires at its base. The bulb's internal filament and supporting leads are visible. An annotation contrasts the relatively low resistance along the circuit wire with the high resistance of the filament, which produces heat and light as current passes through it. The light bulb is identified as a resistor; no wiring defect or improper installation is depicted.
