One lightbulb is marked 25W 120 V, and another 100 W 120 V; this means that each
Question:
(a) Find the resistance of each bulb.
(b) How long does it take for 1.00 C to pass through the dim bulb? Is the charge different in any way upon its exit from the bulb versus its entry?
(c) How long does it take for 1.00 J to pass through the dim bulb? By what mechanisms does this energy enter and exit the bulb?
(d) Find how much it costs to run the dim bulb continuously for 30.0 days if the electric company sells its product at -0.070 0 per kWh. What product does the electric company sell? What is its price for one SI unit of this quantity?
