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...

You plan to take your hair blower to Europe, where the electrical outlets put out 240 Vinstead of the 120 V seen in the United States. The blower puts out 1600 W at 120 V . What could you do to operate your blower via the 240 V line in Europe? What current will be drawn from the 240 V line when the dryer is connected to the 120 V side of the transformer? What resistance connected directly to the...

Problem 4 Part 1: Left diagram. A hobbyist wants to use a microcontroller to turn a lamp on and off. The hobbyist finds a lightbulb that has a rating on it saying "max 100W at 12V" and inserts it into the lamp. So the hobbyist grabs a wn. Unsure of RI = İkSin the circuit as shown. Assuming the microcontroller can output 5mA, calculate how much power is delivered to the light bulb. You can assume the lightbulb acts lie...

Natural gas is widely used as a fuel to cook food and provide heat in homes, to produce electricity in power plants, and to help transport us in cars and trucks. Natural gas has often been collected above conventional oil deposits, but the popularity of collecting this gas using hydraulic fracturing has increased in recent years, particularly in the United States. However, the growing use of hydraulic fracturing, or fracking, has raised environmental concerns, spurring numerous debates and protests across...
