How do you reduce power consumption of a Wheatstone Bridge without changing the bridge resistances?
It seems to me that there are two methods. Reduce the supply voltage to the bridge, or reduce the time that the supply voltage is connected (you could also apply both methods simultaneously). Which is best depends on the details of the application. 1. Reducing the supply voltage: The power consumption of the bridge will be proportional to the square of the supply voltage so halving the voltage will quarter the power consumption. It will also halve the voltage at the detector for any given imbalance so, to maintain the same resolution, the sensitivity of the detector needs to be increased by the same factor as the voltage. Clearly there are limits to this as the imbalance signal will eventually be lost in noise. 2. Reducing the time the supply is connected: It is possible to pulse the supply voltage and the power consumption will be reduced in proportion to the duty factor. Clearly the detector must be fast enough to take a reading during the time that the supply is connected. This might be done using a microcontroller - an output controlling the supply to the bridge and an A/D input to measure the imbalance signal.
What size generator 1200 amps?
First you need to specify what voltage you require the generator to supply...Lets Assume its 240 Volts AC. Watts=Volts x Amps so 240x1200= 28.8 Kw. Then you have to take the efficiency of the generator into account. Mechanical power in is usually quite a bit more than the electrical power you get out...The difference is mostly the mechanical and thermal losses added together. If we say the generator is 70% efficient then you will need a generator 30% more powerful to supply a constant 1200 Amps...Thats a generator of about 38-40 Kw.
How do you wire into a kill switch?
You have to get into the wiring between the stator and the coil to break the power side or to take the power side to gnd and stop the coil from charging. If your still guessing its best to take it to a small engines place and let them do it for $20.
What safety precautions apply to overloaded power points?
Overloading power points is a fire hazard, so it’s important to take precautions. Use surge protectors to manage excess current and avoid plugging in too many high-wattage devices at once. If an outlet feels hot or sparks, unplug everything immediately. Distribute appliances across multiple outlets instead of relying on a single one. Unplug devices when not in use, and if you frequently need extra outlets, consider installing more circuits or using a professionally rated power strip for safety.
What would happen if you tried to operate a dc permanent magnet motor from an ac supply?
Apart from a lot of loud humming, the motor would not turn, it would take a lot of current and, if the circuit breaker did not trip to cut the supply of current, it would probably overheat or might even catch on fire.
The fan in a 250-watt power supply is malfunctioning. what action should you take?
Remove and replace the power supply.
What is the first step you should take when testing a power supply?
You first have to know the type of power supply your are testing. Then you could test whether the power supply is receiving anything from its source. Next check if it is giving any output.
What is the power supply for?
The computer's power supply powers the computer or any other device. If you want more about power supplies take a look at the link provided below.http://en.wikipedia.org/wiki/Power_supply
How to check the power supply section of motherboard not the smps?
You should not bother to check any power supply in the motherboard. You need to take the motherboard to service centre if faulty.
What approach can you take if your computer simply does not power on and there is no lights on?
Check the power supply, if its good then your bios might be at fault.
How are series circuits and parellel circuits alike?
Both take current and energy from the power supply and dissipate power.
How is a series circuit and a parallel circuit alike?
Both take current and energy from the power supply and dissipate power.
Can the power supply cause the computer to be difficult to turn on?
Yes. If the power supply is of a low wattage and has too many pieces of hardware connected to it, it can. Try buying a power supply with a wattage over 300. One thing to check before replacing the power supply is the voltage selector in the back. If you use 120 volt power, then setting the power supply to 240 volts will cause the PC to only get half of the power it needs. External peripherals with their own power supply will not impact the power supply or current in the computer. Printers and monitors usually get their power from the wall socket, not the computer, and the same goes for external modems that plug into the wall. Keyboards and mice take negligible power.
What is the problem of your lg21sa3rl-l4 tv no power supply?
i had the same problem just take it to an expert
Do all apple macs take 100V-240V power supply?
only the iMac and the mac Pro
What is Redundant Power Supply?
A redundant power supply is two or more units in one package, where each can supply the full amount of power to the system, such that if one fails, the other will take over and the system never goes down. In most modern redundant power supplies, the dead one can be replaced while the system is still running, called hot-swapping.
Why do the Taliban take things from afghans?
In order to strike fear into the public and implicate power. They also do it to supply themselves.
