What determines current in a generator?
If the generator above were connected to a circuit of resistance R = ohms, the electric current would be I = V/R = amperes for velocity perpendicular to B. The power supplied to the circuit would be P= VI = watts.
What determines maximum current?
The resistance of the coils can determine the maximum output current. But there are other factors that generally put a limit on the maximum current. jms has stated some of these. Also the electrical machine has effective inductance which is sometimes called synchronous reactance.
Can you measure the amount of current produced by your generator How?
The most foolproof way to measure current is to measure the voltage drop across your load and apply Ohm’s law – I=V/R.
How is the current output of a generator determined?
The current output of a generator is determined by its load, as long as the load doesn’t exceed the maximum capacity of the generator’s prime mover (engine) plus the conversion losses of the actual generator.
How many volts and amps does a generator have?
All generators are rated according to their capacity to produce electrical power in either watts or kilowatts. We also use Voltage (volts) and Amperes (amps) as required. Norwall Power Calculator: How Much Power Do You Need? A portable generator supplies electric current (amps) at 120 and 240 volts.
How are generators rated in Watts and kilowatts?
Generators are rated in Watts or Kilowatts to express how much work they can do. Just as an athlete might put out a burst of extra energy in a sprint for a few seconds, a generator can do the same thing and put out a surge of extra power for a few seconds.
What is the power factor of a generator?
When the rating is in kW, you also need to specify the power factor cos (Φ), which is a number between 0 and 1. You can use approximately 0.80, if the load consists of motors only. For purely resistive loads the power factor cos (Φ) is 1.
