The resistance of an incandescent lamp is measured as 110 ohms. The lamp is then inserted in a DC circuit and it is noticed that as the voltage increases the resistance also increases. How do you explain this apparent contradiction with Ohm's law? Why does the lamp resistance increase with voltage?
