You are cooking breakfast for yourself and a friend using a 1,220-W waffle iron and a 530-W coffeepot. Usually, you operate these appliances from a 110-V outlet for 0.500 h each day. (a) At 12 cents per kWh, how much do you spend to cook breakfast during a 30.0 day period? $ (b) You find yourself addicted to waffles and would like to upgrade to a 2,440-W waffle iron that will enable you to cook twice as many waffles during a half-hour period, but you know that the circuit breaker in your kitchen is a 20 A breaker. Can you do the upgrade? O Yes O No Give the current that this new waffle iron (along with the coffee pot) draws to support your answer. ATaking R = 1.40 kn and & = 340 V in the figure shown below, determine the magnitude and direction of the current in the horizontal wire between a and e. magnitude X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. mA direction from a to e R 2R b + + 28 4R 3R
