- A stationery shop use the following electric appliances: (i) Four Air Conditioner of rating 1900 W for twelve hours each day (ii) Two Electric Freezer of rating 1500W each for 24 hours each day (iii) Ten electric tube lights of rating 20W each for 12 hours each day. Calculate the electricity bill of the stationery shop for the month of November 2020 if the cost per unit of electric energy is 15 Bz/ kWh. (i) Electrical Energy(in kWh) consumed by four Air conditioners of rating 1900 W for 12 h of each day= (ii) Electrical Energy(in kWh) consumed by two Electric Freezers of rating 1500 W for 24 h of each day= (iii) Electrical Energy(in kWh) consumed by ten Tube lights of rating 20 W for 12 h of each day = (iv) Total energy(in kWh) consumed in the month November'2020 = (V) Electricity bill(in riyals) for the month of November'202 =Compare the energy consumption of two commonly used items in the household. Calculate the energy used by a 1.00 kW toaster oven, W toaster, which is used for 5.80 minutes, and then calculate the amount of energy that an 11.0 W compact fluorescent light (CFL) bulb, Wight, uses when left on for 10.50 hours. W toaster = kWh Wlight = kWhA refrigerator using 1028 W runs one-third of the time. How much does the electricity cost to run the refrigerator each month (30 days) at 29¢ per kWh?
- A hair dryer is rated at 1850 W. Assuming there are 30 days in a month, what is the monthly cost of using the hair dryer for an average of 12 minutes every day if you are charged 20 cents for every kW-h? $ 222One 9-volt battery contains 19.7 thousand joules of energy. A 4-pack of 9-volt batteries cost $10.31 at Lowe's. Estimate the cost of battery energy in dollars per kilowatt-hour. Energy conversions are available in Section 2.2 of the textbook. Round your final answer to the nearest $10 per kilowatt-hour.A car battery that has 13.8 V moves 58, 000 C of charge. What is the energy output of the battery? b с Od 8*10^5 J 40 J 4,000 J 800 J
- The flash unit in a camera uses a special circuit to "step up" the 3.0 V from the batteries to 360 V , which charges a capacitor. The capacitor is then discharged through a flashlamp. The discharge takes 10 μs , and the average power dissipated in the flashlamp is 1.0×105 W . What is the capacitance of the capacitor?Cost of Electricity A refrigerator is an appliance that is left running all the time. In New Orleans, Louisiana, the average residential electricity rate charged by Entergy is 9.82¢/kWh. Using this rate, how much will it cost to operate a refrigerator that requires 220 Watts in one month. You can use the following steps: 1. Convert power to kW = 2. Time (in hours) in one month (30 days) = %3D 3. Energy consumption (Power x Time) = 4. Cost (Rate x Energy) in dollars =The 90 µF capacitor in a defibrillator unit supplies an average of 6500 W of power to the chest of the patient during a discharge lasting 5.0 ms. To what voltage is the capacitor charged?
