Problem: The tungsten filament in an incandescent light bulb has a resistance of 1.5 ohm when the bulb is not turned on at 20°C. When the bulb is connected to a voltage of 3.7 V, a current of 0.19 Amp flows through it.
Part A: What is the operating temperature of the filament?
Please show all work and steps to find the operating temperature of the filament.
