A 300-W light bulb is left on for 14 h. Calculate the electrical energy (in MJ) 2 points consumed by the bulb. Show your work. Your answer A family uses an electric frying pan with a power rating of 1.20 X 103 W. 2 points Although the pan is thermostatically controlled, its element was drawing power for 6.30 X 102 minutes in a period of one month. Calculate the electrical energy in KW-h used by the pan during the month. Show your work. Your answer Explain why ultra-high voltages are used to carry electricity over transmission 1 point lines. Your answer Explain why a DC electrical source connected to the input of a transformer 1 point cannot induce any electricity flow from the transformer's output. Your
