What is the difference between a variac and a rheostat?
These devices could, in theory, be interchangeable. Variac is a (typically single coiled) variable transformer, whereas rheostat is a variable resistor. Although they may look just the same, they differ in one aspect - wire resistance. It should be as low as possible for variac, but it can differ on rheostats. So-you can use wire rheostat as a low efficiency variac and you can use wire variac as ridiculously huge rheostat, resistive range of which serves no practical purpose.
What is the condition for maximum transfer theorem?
For maximum power transfer the load resistance should be equal to the source resistance.An often misunderstood theorem. It applies strictly where one wishes maximum power transfer.It was misused for example in early power systems by trying to match the generator resistance to the load resistance.And it has little application in audio systems, where Power is much less important than Distortion. [for least distortion, the output impedance of the amplifier should be less than 10% of the impedance of the load.]
At what angle should a slingshot be oriented for maximum altitude?
You should point it at a 40 degree angle.
What is the maximum amount of mechanical energy that can be converted to heat?
Why should there be a maximum? If there is friction, ALL the mechanical energy will eventually be converted to heat.
Which one best describes the position you should be in to give maximum clearance for rear end swing?
Which one best describes the position you should be in to give maximum clearance for rear end swing
When starting up the generator you should crank the engine longer than?
15
When starting up the generator you should not crank the engine longer than?
15 Sec
If the heater in the punto not blowing?
Replace the rheostat under the passengers footwell. Should be two screws on a plastic casing pull it down and pop the rheostat out and replace.
How long can the maximum ampere rating on a generator be exceeded?
Sometimes only seconds, it depends on the way the manufacturer rated the "maximum" capacity. In general, electrical equipment should be operated at no more than 1/2 of a maximum capacity.
How to compute the minimum load of 16 MW generator?
A generator, rated at 16 MW, should be able to continuously supply a load of 16 MW. You don't need to compute its 'minimum load', because the minimum load will be zero watts! In other words, you can run the generator with no load whatsoever if you wish to waste fuel.The point is that the power supplied by a generator is determined by the load, NOT by the generator itself -so it is important that the generator is capable of supplying the maximum load applied to it. A generator's 'rated power output' simply tells us the maximum load it is capable of supplying.
Is Your Standby Generator Big Enough?
When selecting a standby generator, you should not only consider the wattage requirements of any equipment connected to the system, but you should also factor in the starting wattage of any electric motors. The typical electric motor draws three to five times the current when starting than it does when running, so it's important to have a big enough generator to avoid burning out any motors.
Understanding Home Generator Sizing?
A home generator can be a useful tool in emergencies. When buying a generator, it's important to find a unit that will power all the necessary appliances and utilities in a home. Homes that have an electric pump for well water should have a 5 kilowatt generator for maximum performance. Homes with a municipal water supply will only need a 3 kilowatt generator. A whole-home generator will usually be 10 kilowatts and will require professional installation.
Will 2500 generator run a laminating machine 240v 10a 50hz?
Yes. 240 volts at 10 amps is 2400 watts. The generator is 2500 watts maximum. If the generator is 2500 peak power it may not run it very long. If the continuous power rating is at least 2400 watts it should be OK.
Is there such thing as a sump pump connected to a generator?
Yes, a sump pump can be connected to a generator to make it operate. Keep in mind that the starting current of the pump motor could be 300% of the running current and the sizing of the generator should take this into account. If you are looking for the sump pump using a mechanical connection it will connect to the engine and not to the generator.
What actions to be taken should a main generator circuit breaker stay connected?
I don't understand the question. <<>> If your generator's main breaker does not trip when an overload occurs on the generator's output the breaker's trip setting needs to be looked at. Usually the molded case breaker's face cover can be removed. This will allow you access to the trip settings. Set the overloads to the maximum generator's output. The short circuit setting should be set at 250% of the maximum generator output. If these parameters can not be met on the existing breaker there might be a chance that the breaker has been changed out at some point in time and the wrong breaker was installed at that time. This scenario happens quite frequently on remote operations where the service has to be maintained and the site doesn't have a second back up generator. The site supervisor usually says "just make it work".

What is the physical meaning of power angle in a power system?
a curve drawn for power against load angle maximum power occurs at load angle of 900 maximum power will be transffered from sending end to receiving end when the reactance is 1.732 times its reactance
