Few questions on electricity (Please check my answers)?

1. How is electricity for houses generated at the power plant? My answer: At thermal power stations where heated water turns into steam which rotates a steam turbine, driving the electrical generator. 2. How is that electricity transferred? How can you estimate the voltage of a power line by looking at it? My answer: Through […]

turbine speed, pressure and power output?

“The amount of steam going through the turbine (mass per unit time) determines the power output, it is a direct input of energy into the machine and electrical power is a direct output of the machine. So the load from the generator is a mechanical braking force on the turbine that keeps it at a […]

Physical Science Help?

Which describes the use of a nonrenewable energy source? burning coal to create steam in power plants turning turbines with water held behind dams burning plant wastes to run generators Thanks!

Why is burning wood not considered Zero Emissions?

Trees when growing convert CO2 to O2, and when burning the wood it simply balances the equation. Meaning, no additional CO2 is generated/released. So why is this not considered Zero Emissions (aka “green”)?? Also, why are we not encouraging power plants to burn wood for use in their steam turbines generators?? Firewood even in large […]

chemistry help? thanks.?

Electrical power plants and ships commonly use steam to drive turbines, producing mechanical energy from the pressure of the system. The rotating turbine is connected to a generator that produces electricity. Steam enters a turbine at a high temperature and pressure and exits, still a gas, at a lower temperature and pressure. Determine the final […]

power plant question?

if power plants burn coal to create steam that turns generators to make electricity, why can’t they boil water on huge heating grids? that makes steam too.

powerplant generators?

hi, i would like to ask some questions about generators mechanical energy to electric energy generators such as the ones used in hydro electric dams, steam powerplants, gas turbine power plants and wind turbines. are there different classes of these generators? if so, what are they, and what power out put in mega watts do […]
