A generator never develops more KVA than is being used. However the speed of the motor is not always the speed of the generator. The motor speed depends on the number of poles it has, and the generator speed depends on the Hz of the system.

Basically YES.... Electricity flows in a complete circuit, an electron leaves the power supply passes through the circuit and returns to the power supply. What flows out of a say a battery positive terminal travels through the curcuit and returns to the negative side of the battery. A battery is a power source, and so is a generator or alternator thus the same principle applies. What current flows out of the power supply has a matching current flow returning.

For your question about a motor and generator coil...

With nothing else connected the two coils would form a simple series circuit. Kirchoff's laws state current flow in a series circuit is the same for all components.

Because wire has some resistance there will be some voltage drop across the wires so the motor coil will have slightly less voltage but the current flow from the generator coil through the wires and motor coil will be the same as this would be a simple series circuit.

In this scenario it is more of a mechanical problem than an electrical problem. The speed has nothing to do with power consumption. Let us analyse it a little further. You are talking about ideal condition.In ideal condition if the motor is running at 10000rpm it requires no power to maintaion that speed. It should keep running at the same speed even if you cut the supply to the motor. But in practical condition the motor stops immediately. It means there is power loss by means of friction or by some other means. This power requirement can be zero to any value.





Now let us consider the case of a generator.A generator is running at no load at 5000 rpm.now you connect a motor,light or anything to this generator. Immediately the speed of the generator will come down. Now you have to pump more fuel into the generator to maintain it's speed. So the speed has nothing to do with power generation or consumption.

generally yes they are the same but if the motor is located a long ways away there are losses in the wires so generation is higher than consumption.

Hi, electrical isn't really my forte so forgive my ignorance on this subject. so my question is: will two identical coils, one used in a generator and one used in a motor both generate and consume the same amount of current in ideal conditions if the generator and the motor both run at the same speed?





Thanks in advance:)
