- The generator of a car idling at 1200 rpm produces 14.2 V. What will the output be at a rotation speed of 2800 rpm, assuming nothing else changes?In a sunnier location than Eugene, the sun shines for an average of 2000 hours per year. A home owner installs solar panels that generate 3.5 kW from these panels when the sun is shining. If the local electric utility charges $0.15 per kWh, how much money do the solar panels save the home owner per year? Give the answer to the nearest dollar.How many watts will a motor use if the voltage is 240 volts and the motor is drawing 40 amps of current?
- The interior lighting of refrigerators is provided by incandescent lamps whose switches areactuated by the opening of the refrigerator door. Consider a refrigerator whose 40 Wlightbulb remains on continuously as a result of a malfunction of the switch. If therefrigerator has a coefficient of performance of 1.3 and the cost of electricity is Rs. 7 perkWh, determine the increase in the energy consumption of the refrigerator and its cost peryear if the switch is not fixed. Assume the refrigerator is opened 20 times a day for anaverage of 30 s.Still in DC Steady State, ℰ=11 volts, R1=46 Ω, R2=51 Ω, and R3=37 Ω, and L=6 Henry. Calculate I1.Still in DC steady state, ℰ and R₁ are unknown, but set to allow I₁ = 4 A, R₂ = 6 Ω, and R₃ = 9 Ω. Calculate I₂.
