What else can I help you with?
Hans Christian Oersted discovered that electricity could produce magnetism.?
TRUE
Is salt water a condutor of electricity?
Yes, it is true.
True or false when a magnet is moved electricity is formed?
True. When a magnet is moved near a conductor, such as a wire, it causes a change in the magnetic field around the conductor. This change induces an electric current to flow in the conductor, resulting in the formation of electricity.
Is true Metals are not good conductors of electricity. An electrolyte solution conducts electricity. Wood is a good conductor of electricity. Nonmetals are good conductors of electricity.?
1. Metals are good conductors of electricity.2.An electrolyte solution conducts electricity.3. Wood and nonmetals are not good conductors of electricity.
True or false precipitation usually comes ahead of a warm front?
It is true to say precipitation usually comes ahead of a warm front.
How can moving water be used to produce electricity true or false?
True. Moving water can be used to produce electricity through hydropower. This is done by capturing the kinetic energy of flowing water and converting it into electrical energy using turbines and generators in hydropower plants.
Is it true that the majority of the worlds electrical demands are met with hydroelectric generators?
No, it is not true that the majority of the world's electrical demands are met with hydroelectric generators. While hydroelectric power is a significant source of renewable energy and contributes a substantial portion of global electricity generation—about 16%—it is not the largest source. Fossil fuels, particularly coal and natural gas, still dominate the energy mix worldwide, providing the majority of electricity.
When it comes down to it selfishness causes most collisions and violations. True False?
True
Why is nuclear power generators popular?
I thought the opposite was true, that they are not popular!
Where and who found electricity?
Where do we get electricity?Well, electricity comes out of holes in the wall, correct? True, but what makes electricity, and gets it to those holes?GeneratorsElectricity is created by generators. These generators convert mechanical, chemical, or other forms of energy into electrical energy. The most common generator is mechanical and creates electricity by rotating a large magnet within a huge coil of wire. Solar generators convert light energy directly to electrical energy.What drives the generators?The vast majority of electric generators in the United States use turbines to rotate the magnets within the coil. A turbine is a machine for generating rotary mechanical power from a flowing stream of steam, wind, or water. The gas or liquid flows over blades on a shaft causing it to rotate.Most turbines are driven by steam. Wind turns large propeller blades that rotate the magnets in the coil. Water flowing through dams drives turbines that rotate the magnets in the coil.
What is the difference between wind mills wind generators or wind turbines?
The true difference is use. A wind mill is traditionally used on a farm to power the house where as a wind generator/ turbine is used for electricity on a much higher amount. All of these things are using the power of wind to create electricity/ power for something.
Is it true that large generators use armature similar to those in a motor?
yes
Is it true that in the US you use fossil fuels for most of your electric energy?
Coal is the main fuel for electricity.
Is it true that Most rain and snow comes from evaporation of lakes and rivers?
No. The oceans
What is Hypothesis of electricity?
We are long past the hypothesis stage, with regard to electricity, which is a very well understood phenomenon at this point. If you would like to know about the history of scientific investigation of electricity, there were a number of hypotheses, including the hypothesis that lightning is a form of electricity (which is true) and that nerve impulses are also a form of electricity (also true) and that electricity can be generated by some types of chemical reactions (also true) and that electricity can be used to make the Frankenstein monster come to life (not true).

Is it true that an electrical insulator does not allow electricity to pass through it?
Yes, it is true.
