Final answer:
True, generators convert mechanical energy into electrical energy by inducing an electromotive force, facilitating the flow of electricity.
Step-by-step explanation:
The statement that a generator does not actually produce electricity but merely produces an electrical pressure which causes electricity to flow is true. An electric generator converts mechanical energy into electrical energy; it does this by rotating a coil in a magnetic field. This rotation induces an electromotive force, or emf, which is the electrical pressure that causes current to flow through a circuit. Real-life generators can utilize various mechanical energy sources such as hydropower, steam from burning fossil fuels, or wind to turn the coil within the generator's magnetic field, creating alternating current (AC) voltage.
