How many volts does it take to power an audio speaker?
A 50 watt, 8 ohm speaker requires 20 volts to drive it to full power. Watts equals volts and amps, while volts equals amps times ohms.However, the 8 ohm rating is actually a minimum rating, and depends on frequency. Also, driving a speaker to full power on a continuous basis is not good for the speaker. (Or for the ears, either.)
How many volts does the average AC power generator make?
This depends on what you are meaning by "Average". A typical small generator you can throw in the back of a truck will produce 120 volts, some can do 240. Building backup generators would produce whatever voltage is needed for that building (if it's a plant that using 480 volts, it will produce 480 volts). "Large" Wind turbine generators often produce 600-1000 volts; good sized power plants (100MW and up) will typically have a terminal voltage of 10-30kV.
Can a 780 watt uninterruptible power supply handle a 12.5 amp pump motor at 120 volts?
Volts * Amps = Watts 120 Volts * 12.5 Amps = 1500 Watts Doesn't sound like a good idea.
How much energy does a blow dryer take?
They come in different sizes, and power ratings. Look at your dryer; somewhere it should have electrical specifications. These should either include a power (in watts), or volts and amperes separately. If volts and amperes are listed separately, multiplying them gives you a good idea of the amount of watts consumed. Note: watt is a unit of power, not of energy. You need to multiply that by the time you use the device, to get energy: joules = watts x seconds
What are some good thing about nulear power plants?
POne good thing is that they provide a decent amount of power
How much volts does a small light bulb need to be powered?
110 volts is what comes out of an average wall socket in America. A 100-watt bulb would be powered by 110 volts. You need to be more specific in your question to get a good answer. Small can't be measured.
1995 buick regal no break lightsswitch is good and fuse is good?
Check for 12 volts at the hot side of the brake light switch. If you have 12 volts at that point depress the brake pedal and check for 12 volts at the cold side of the switch. If you have power there go to the back and check the bulbs, be sure they are good. If the bulbs check okay and the wiring looks good the problem may be in the signal switch under the steering wheel.
What resistor to drop 2V to 1 1.5V?
Doing it with a single resistor is not a good idea because it can only be done with exactly the right amount of current. If the current is 1 amp, for a voltage drop of 10.8 volts you need 10.8 ohms (volts/amps).
How many volts does an AA battery produce?
A good AA battery has about 1.5 volts across it.
What is a 210 vac plug in?
This a electrical plug that is designed to be used with 210 volts of alternating current(The power in your house). Most of the time you will not be able to find a 210 vac outlet. the good new is when they are designed, there is an allowance of + or - 10% so they can be run almost anywhere in the world. So you are safe from 191 volts to 231 volts.
How much electrical resistance does a big city have?
The resistance is simply the value of resistances of all electrical equipment connected in Parallel by all consumers in a big city.The answer is amazingly accurate, if we have the average power consumption (Megawatts-MW) figure from the power company at any time of the day.Suppose a big city is consuming 100-MW at a given time. Assuming we use 100 volts AC at consumer homes, then at any given moment the instantaneous resistance (R in ohms) of the city is simply given by the formula:Power(watts) = (Volts x Volts) / Resistance (R in ohms)..........or,P=V2/ R, therefore,R = V2/P (ohms)......... then,If:V=100 volts (ac)P= 100,000,000 wattsThen:R = 100 x 100 / 100,000,000 = 0.0001 (ohms)(make sure to use only watts, volts and ohms in the formula above).Good Luck !The resistance is simply the value of resistances of all electrical equipment connected in Parallel by all consumers in a big city.The answer is amazingly accurate, if we have the average power consumption (Megawatts-MW) figure from the power company at any time of the day.Suppose a big city is consuming 100-MW at a given time.

How much does a laptop power adapter cost on average?
The average cost of laptop power adapters is about $80 to $100 USD. You can find more affordable power adapters, but the quality and life span will not be as good.
