Part C Compact fluorescent bulbs are much more efficient at producing light than are ordinary incandescent bulbs. They initially cost much more, but last far longer and use much less electricity. According to one study of these bulbs, a compact bulb that produces as much light as a 100 W incandescent bulb uses only 23.0 W of power. The compact bulb lasts 10000 hours, on the average, and costs $12.00, whereas the incandescent bulb costs only $0.74, but lasts just 750 hours. The study assumed that electricity cost $0.090 per kilowatt-hour and that the bulbs were on for 4.0 h per day How much do you save over 3.0 years if you use a compact fluorescent buib instead of an incandescent bulb?

An immersion heater used to boil water for a single cup of tea plugs into a 120 V outlet and is rated at 300 W.a. What is the resistance of the heater?b. Suppose your super-size, super-insulated tea mug contains 400 g of water at a temperature of 18°C. How long will this heater take to bring the water to a boil? You can ignore the energy needed to raise the temperature of the mug and the heater itself.
The capacitor in the circuit shown is fully charged by a 24 V battery. The switch is closed at t = 0. At sometime after the switch is closed, the voltage across the capacitor is measured to be 10 V. What is the current in the circuit at this time, in Ampere? C = 3.0 µF, and R = 2.0 02. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Cil
When the switch is in position a below, the battery charges the positive parallel plate of the capacitor to Q = 900 µC. The switch then swings to position b, the charge Q flows through the resistor R, and the capacitor’s stored energy U is turned into heat energy. Assume the capacitor has capacitance C = 8.00 µF. Use conservation of energy to find the amount of heat (in Joules) produced during the capacitor’s discharge.
Question A3 A large capacitor of 3000 µF is charged by a constant current. After 1 minute it reaches a voltage of 100 V. At that voltage, the charging circuit is disconnected. a) Calculate the charging current. b) A second identical capacitor is connected across the capacitor, using wires with 1 kN re- sistance. Sketch a graph of the voltages on the two capacitors as a function of time, with appropriate numbers and units marked on the axes.
