Suppose you operate a 100 W lamp continuously for 1 week whenthe power utility rate is 20cents/kWh. Show that this costs$3.36. _________________ I know that a kW=1000W. The lamp can operate for 10 hours to reach 1kw which wouldcost .20cents. 100W lamp * 10 hours = 1000W or 1 kW. $3.36/.2=16.8 16.8 hours @ .20cents per hour Is this how you would figure this? I can't find anythinglike it in the book. Suppose you operate a 100 W lamp continuously for 1 week whenthe power utility rate is 20cents/kWh.
