Homework Statement
The turbine produces current that is at 12kV. To lessen the problem of Ohmic heating, a transformer steps up the voltage to 138kV for power line tranmission.

A turbine is a machine that converts the energy of a moving fluid (such as water, steam, or air) into mechanical energy by turning a rotor.
A turbine produces current by using the mechanical energy from the moving fluid to turn a rotor, which is connected to a generator. The rotation of the rotor in the generator produces electricity, which can then be used as current.
Ohmic heating, also known as Joule heating, is the process by which an electric current passes through a conductor and produces heat. This occurs because the resistance of the conductor causes the electrical energy to be converted into heat.
In turbines, Ohmic heating is used to heat up the conductor in the generator, which in turn produces the mechanical energy needed to rotate the rotor and generate electricity. This heating effect helps to maintain the continuous flow of current in the turbine.
Using turbines for current production has several benefits. Turbines are a renewable energy source, as they use the natural flow of water, wind, or steam to produce energy. They also have low operational costs and do not produce any emissions, making them environmentally friendly. Additionally, turbines can be used in remote locations, making them a versatile option for electricity production.
