Bulb resistance calculation

The small bulb's socket has a reading of 6.3 V/0.3 A, which applies to its filament when the bulb is on. Determine the electrical resistance of the fiber under the given condition (the temperature of the fiber corresponds to about 2800 °C)

Final Answer:

R =  21 Ω

Step-by-step explanation:

U=6.3 V I=0.3 A   U = R   I  R=IU=0.36.3=21 Ω
