A 430-W space heater is designed for operation in Germany, where household electric outlets supply 230 V (rms) service. What is the power output of the heater when plugged into a 120-V (rms) outlet in a house in the United States? Ignore the effects of temperature on the heater's resistance.
38. (II) You buy a 75-W lightbulb in Europe, where electricity is delivered to homes at 240 V. If you use the lightbulb in the United States at 120 V (assume its resistance does not change), how bright will it be relative to 75-W 120-V bulbs? Hit: Assume roughly that brightness is proportional to power consumed.]
A 12-V battery causes a current of 0.80A through a resistor. A) What is its resistance? B) How many joules of energy does the battery lose in a minute? You buy a 75-W lightbulb in Europe, where electricity is delivered to homes at 240 V. If you use the lightbulb in the United States at 120 V (assume its resistance does not change), how bright will it be relative to 75-W 120-V bulbs? [Hint: Assume roughly that brightness is proportional to...
