When saltwater is flowing through a pipe, does it constitute an electric current?arrow_forward(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) . A simple electric circuit consists of a constant-voltage power supply and a variable resistor. What effect does reducing the resistance have on the current in the circuit and on the power output of the power supply?arrow_forwardIn 2019, residential customers in the United States purchased an average of 10,649 kilowatt-hours of electricity. (a) What is the average daily electricity consumption for a residential customer? (b) How many 50W light bulbs could you run flat out for a 24hr period with this electricity? (c) If this energy was instead only used to run a 1,000W microwave after how many hours would the microwave stop?arrow_forward
- A ceiling fan operates at three speeds, using 120 V of electricity from the wall. At low speeds, it uses 0.25 A. Calculate the resistance needed to generate that current. Then in 1-2 sentences, describe how the resistance would change at medium and high speeds if larger currents are needed at those speeds. Your answer should include the calculated resistance and a sentence describing your reasoning.arrow_forwardplease answer the following A) A lightning stroke lasts 0.02s and involves a flow of 298 C. What is the current? B) An electric clothes dryer is rated at 2,600 W. How much energy does it use in 35 min?arrow_forwardWhen 3000N boat is moving at 3m/s, the motor conks out. How much farther will the boat glide, assuming its resistance to motion is 30V N where V is in m/s?arrow_forward
- Whale and Kanmuro are two islands located in the Chimera archipelago. These two are separated by a distance of 20 miles. A power link is to be established between them. The power link delivers a maximum power of 547 megawatts at full capacity with an operating voltage of 554 kilovolts. Note that 1 mile is 1.5 kilometers. Solve for the current at full power capacity in kiloamperes. Express Answer into FOUR decimal places.arrow_forward(Indicates a review question, which means it requires only a basic understanding of the material to answer.

If a new material is found that is a superconductor at all temperatures, what parts of some common electric deices would definitely not be made out of it? Explain.arrow_forward
- The prefix “mega” (M) and “kilo” (k), when referring to amounts of computer data, refer to factors of 1024 or 210 rather than 1000 for the prefix kilo, and 10242 = 220 rather than 1,000,000 for the prefix Mega (M). If a wireless (WiFi) router transfers 150 Mbps of data, how many bits per second is that in decimal arithmetic?arrow_forwardCheck your Understanding Repeat the calculations from the previous example for I0=0.040A .arrow_forward(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) . Make a sketch of an electric circuit that contains a switch and two lightbulbs connected in such a way that if either bulb burns out the other still functions, but if the switch is turned off, both bulbs go out.arrow_forward
