A certain light bulb is rated at 60 W when operating at an RMS voltage of 120 V. What is the resistance of the bulb?
A certain lightbulb is rated as 60.0 W when operating at an arms voltage of 120 V.
(a) What is the peak voltage applied across the bulb?
(b) What is the resistance of the bulb?
(c) Does a 100-W bulb have greater or less resistance than a 60.0-W bulb? Explain.
How much power does a 60w/120V incandescent light bulb dissipate when operated at a voltage of 115V? Neglect the bulb's decrease in resistance with lowered voltage.
