What are the properties of energy? Give example of electrical, mechanical, chemical, thermal and electromagnetic energies. Explain Faraday’s law of electromagnetic induction. Does the transformer draw any current when its secondary is open? Can 50-Hz Transformers Be Operated at 60 Hz & Vice versa? Suppose that cost of electrical energy is $0.32 per kilowatt hour and that your electrical bill for 30 days is $180. Assume that the power delivered is constant over the entire 30 days. (a) What is...
7. Two light bulbs with ratings of 40 W and 100 W are plugged into sockets supplying 110 V. A) Calculate the resistance of each. Which has more resistance? The more resistance. (Notice that voltage is fixed) W bulb has B) If the 100 W bulb is operated continuously for 2 full days and electric energy costs $0.12 per kWh, how much does it cost? Convert W to kW multiply by the number of hours to get kW.h multiply by...
