You mean MW (megawatts) not mw (milliwatts). If it is generating 200 MW, that is 200,000,000 watts, at 25,000 volts, the current is given by watts/volts = 8000 amps.

A power stations output is 200mw and 25000volts assuming they only had 1 generator what would the current be flowing out of the wires of the power station?

Current is measured in Amps, with Ohms law we know Amps are equal to Watts divided by Volts or A=W/V in this case the formula would be: 200,000,000/25000= 8000 Amps


What energy transfers generate electricity in a water dam power station?

It is the transfer of mechanical/physical energy to electrical energy. The flowing water rotates a turbine which is attached to a generator and in turn creates an AC field.


When you are creating a generator what determines how much current is generated?

You don't generate current. You generate voltage, and the amount of current that leaves the generator is determined by the devices that are designed to run with that voltage, and draw their operating energy from your generator. You choose the size of the materials used to construct your generator based on the maximum amount of current you expect it to be asked to deliver by its users. But the actual current at any moment will depend on how many people are using it for their supply, and what kind of appliances they're operating. If nobody is using power from your generator, or the output cables are disconnected from it, then you can run it all you want and the current will be zero. Before you decide on the final design and go out for bids to construct your generating station, you might like to review the topics of voltage, current, power, and energy, and get them straight in your mind.


What are examples of mechanical to electrical energy?

A steam turbine/generator in a power station, a small gasoline powered generator, or a 12v alternator in your car driven by the engine.


What is needed to generate AC electricity?

An AC generator (Alternator). A rotor is turned into a magnet by what is known as 'excitation' current. The rotor then induces AC current in the stator windings as it is rotated within it. This is AC, due to the fact that the rotor has a north and south pole, which alternately induces current in the stator windings. The exitation current is provided to the rotor via slip rings. Controlling this excitation current will also control the output power by suitable control circuitry. This is the same principle, whether it is a small domestic generator, a power station, a wind turbine, or a car alternator.
