Which component of a power station is a source of electrical energy?

The generator is responsible for converting mechanical energy into electrical energy in a power station. In a typical power generation process, the turbine spins as a result of thermal energy (from burning fuel, for example) or mechanical energy from other renewable sources like wind or water. As the turbine turns, it is connected to a generator that utilizes electromagnetic induction to produce electricity. The movement within the generator creates a flow of electrons, thereby generating electrical energy that can be sent out to the grid for consumption.

Other components serve different roles. The turbine converts energy from fuel or another source to mechanical energy, but does not generate electricity itself. The transformer is essential for increasing or decreasing voltage levels in electrical circuits but doesn't create electrical energy. The condenser, often used in steam power stations, helps in condensing steam back into water but, like the transformer, does not produce electrical energy. Thus, the generator is uniquely responsible for the creation of electrical energy within the power station.
