6. [-/10 Points] DETAILS OBINPHYS8 7.P.006. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A current of 0.9 A goes through an electric motor for 3 min. How many coulombs of charge flow through it during that time? Need Help? Read It 7. [-/10 Points] DETAILS OBINPHYS8 7.P.010. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The resistance of each brake lightbulb on an automobile is 5.2 0. Use the fact that cars have 12-V electrical systems to compute the current that flows in each bulb if they are connected in series. (For simplicity, assume that the circuit is only composed of one brake lightbulb and the car battery.) A Need Help? Read It 8. [-/10 Points] DETAILS OBINPHYS8 7.P.012. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The resistance of the skin on a person's finger is typically about 22,000 0. How much voltage would be needed to cause a current of 0.001 A to flow into the finger? (This is about enough current to just be felt by most people.) V Need Help? Read It 9. [-/10 Points] DETAILS OBINPHYS8 7.P.025. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A toaster operating on 120 V uses a current of 7.3 A. (a) What is the toaster's power consumption? W (b) How much energy does it use in 9 min? (c) What is the total resistance of the heating element wires? Need Help? Read It 10. [-/10 Points] DETAILS OBINPHYS8 7.P.027. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The generator at a large power plant has an output of 1,900,000 kW at 23,000 V. (a) If it were a DC generator, what would be the current in it? A (b) What is its energy output each day-in joules and in kilowatt-hours? kWh (c) If this energy is sold at a price of 10 cents per kilowatt-hour, how much revenue does the power plant generate each day? $ Need Help?
