- The cost of electricity varies widely throughout the United States; $0.120/kWh is a typical value. At this unit price, calculate the cost of the following. (a) Leaving a 80.0-W porch light on for 2 weeks while you are on vacation. $ 3.23 (b) Making a piece of dark toast in 3.00 min with a 860-W toaster. 0.00516 X Your response is off by a multiple of ten. (c) Drying a load of clothes in 40.0 min in a 5,800 W dryer. 0.464 X Your response is off by a multiple of ten.A 12 volt car battery is being used to power a circuit with a total resistance of 0.5 Mega-ohm. a) What is the power (in watts) being used by this circuit? b) The circuit is switched on for exactly 27.3 days and then switched off. How much energy has the circuit used (in joules AND kilowatt-hours) in this time? c) If the current rate of hydro use is 10.1 cents per kilowatt-hour, how much would the use of this circuit contribute to your hydro bill (assuming that no other charges apply)?00-gauge copper wire has a diameter of 9.266 mm. Calculate the power loss in a kilometer of such wire when it carries 1.00×102 A .
- How much does it cost to run a 1500-W hair dryer for 18 minutes each day for one month (30 days) at a cost of 15¢ per kWh?$QUESTION 6 a) What is the time constant for the circuit shown in the figure below if the value of ε = 12.0 V, R = 21.4 ohm, and C = 39.1 mF.? b) Suppose that the switch is closed and the capacitor starts to charge. How much of the charge will be accumulated on each plate of the capacitor after 3 s of charging? Submit the value of the charge (in mC, with tho decimal places) as your answer.1. With a 1200 W toaster, how much does it cost to make a slice of toast (cooking time = 1 minute)? Electricity costs 4.5 cents per kW.h. 0.135 cents
