1. Power plants typically use turbines to generate electricity by turning generators. Explain how a generator produces electricity.

Expert Solution

A generator is a device that converts mechanical energy into electrical energy.

Generator does not actually create electrical energy, it uses the mechanical energy and it causes movement of

electric charges present in the wire of an external electric circuit and form a electricenergy.

Actually generators  work on the principle of electromagnetic induction discovered by Faraday.

According to Faraday flow of electric charges could be induced by moving an electrical conductor ( ex. a wire

that contains electric charges) in a magnetic field.

This movement creates a voltage difference between the two ends of the wire , which causes the electric charges

to flow, thus generating electric .

In power plants , electricity generators are powered by steam turbines. They spin and propell windmills using

steam.

The steam is made by boiling water using energy released from burning coal or oil,

They rotate the coil of generator and produce electricity by electromegnetic induction as explanned by faraday.

Question 1. Go to random.org. This website is a random number generator. Use it to generate three numbers a, b, c between -10 and 10. Now let your a, b and c be the coefficients of the quadratic function f(x)=ax2 +bx+c. (For example, if the numbers you generated happened to be a = 2,b = 12, c = −1, your function for the rest of the question would bef(x) = 2x2 +12x−1.) (a) Put f(x) into “standard” or “vertex” formf(x)=a(x−h)2...
