In a circuit with a 6 V battery hooked up to a 3 Ohm light bulb what does the current measure?
2 amperes (current = voltage/resistance)
Example of normal distribution?
Male and female blood pressure, IQ, SAT and other test scores, life of a light bulb, weight and height, shoe sizes... Hope this helps!
How many times light on and off in 1 second?
A fluorescent tube turns on and off 60 times a second in north America. An incandescent light is lit by a heated filament, so although the current changes direction 60 times a second to the bulb, it does not have enough time to cool down, so it doesnt turn off.
How much does a 60 watt light bulb use per hour?
Typical home energy cost is 10 cents per kilowatt hour A 60 watt bulb running for one hour uses 60 watt hours .10 X (60/1000) = .006 cents per hour 16.66 60watt bulbs on for one hour would cost 10 cents.
What causes the efficency of a machine to be less than 100 percent?
That means that some energy is wasted. For example, it is quite common for part of the input energy to be converted into useless heat.A drastic example is a traditional incandescent light bulb. Something like 5% of the energy gets converted into visible light. The remainder is radiated mainly as infrared - that is, heat radiation.
