    R= E^2/P = 110^2 = 161.333 Ω The switch is turned on and a current of 682 mA. flows through the lamp filament causing it to radiate energy Incandescently without consumption.

    Operating resistance of bulb equals relatively close to (110V^2)/(75W) = [(12,100)/(75)]Ohms when operated under the same conditions that this type bulb was rated at by it's manufacturer.

    R = 75 / 110^2 ohm

    First find the current....power/voltage = 75/110 = 0.682 amp Resistance = voltage/ current = 110/0.682 = 161.3 ohms.
