Question: A 1 0 0 - W ( w a t t ) light bulb has resistance R = 1 4 5 ( o h m

A100-W(watt) light bulb has resistance R=145(ohms) when attached to household current, where voltage varies as
V=V0sin(2ft), where V0=110V,f=60Hz. The power supplied to the bulb isP=V2RJs(joules per second) and the total
energy expended over a time period 0,T(in seconds)is
U=0TP(t)dt
Compute Uif the bulb remains on for 6 hours.
(Use decimal notation. Give your answer to one decimal place.)
U:
Incorrect Answer
A 1 0 0 - W ( w a t t ) light bulb has resistance
