Measure resistance of light bulb
WebRecord the value of resistance, and replace the light bulb to its original position on the circuit board. You have now measured the resistance of the light bulb filament at room temperature, about 20 0C. At this point ask your instructor to verify that the circuit is equivalent to Fig 2. An incorrectly wired circuit is likely to give
