Question

what is the solution to these question? A light bulb has a resistance of 250 when operating at a voltage of110 V. What is the current in thebulb?
mA A certain lightbulb has a tungsten filament with a resistanceof 18.0 when cold and136 when hot. Assume thatP = IV can be used over the largetemperature range involved here, and find the temperature of thefilament when it is hot. Assume an initial temperature of20°C.

Explanation / Answer

Resistance R = 250 ohm

Voltage V = 110 V

Current in the bulb I = V / R

                                  = 0.44 A

                                  = 440 mA
