A 100-watt (W) light bulb has resistance R = 144 ohms () when attached to household current,

Question:

A 100-watt (W) light bulb has resistance R = 144 ohms (Ω) when attached to household current, where the voltage varies as V = V₀ sin(2π ƒ t) (V₀ = 110 V, ƒ = 60 Hz). The energy (in joules) expended by the bulb over a period of T seconds is

= 5 U = P(t) dt

where P = V²/R (J/s) is the power. Compute U if the bulb remains on for 5 hours.
