A 2.0 cm long tungsten filament in a florescent light bulb has a radius of 0.3 mm. Assume constant 20 degree Celsius temperature during operation of the light bulb. Given that the light bulb is connected to a 6.0 volt battery, calculate the current through the wire. A 10 Ohm resistor is now connected in parallel with the light bulb in the circuit with the same battery. What is the new current in the circuit? What happens to the circuit if the temperature goes beyond 20 degrees?
