The transmission of electrical energy requires very high voltages (for a given load, the higher the supply voltage, the lower the load current). To increase/reduce these voltages, you need Transformers. Transformers are AC machines; they do not work with DC.

What is use of capacitor?
It blocks direct electrical current allowing alternating current to pass
What kind of energy source does a transformer use?
Electrical (alternating current)
What type of current is used in your home alternating or direct?
In North America the electrical system is alternating current at a frequency of 60 Hertz. Europe and the UK use alternating current at a frequency of 50 Hertz. Direct current systems are obsolete because of the inability to transmit the voltage over long distances.
Did Thomas Edison argue that your electrical system should use direct current because he felt that alternating current was dangerous?
Very strongly. Edison went so far as to make a movie of an elephant being executed with AC.
Wall outlets use what kind of current?
alternating current
How did Nickola use electricity?
Nikola Tesla was the inventor of the alternating current light and power system in use all over the world today.
What does a transmission system at a radio station use to convert a direct current into a high frequency alternating current?
a high power, often class C amplifier.
What are the 2 basic types of currents?
The main division is between alternating current (AC) and direct current (DC). AC is universal now for domestic and industrial supply, but DC used to be used in some places in the early part of last century. Automobiles use DC at 12V which is I think universal now. AC in domestic use can be at 50Hz (Europe and many other places) or 60Hz (North America), and can be at either 240V or 120V.
What is use of rectifier?
Rectifier is used to convert alternating current to direct current.
What voltage is used by a car cigarette lighter?
A car cigarette lighter uses 12 volts direct current. Car electrical systems use 12 volts direct current verses the 120 volt alternating current use in most household situations.
Do you use static electricity in your homes or current electricity?
electric current (alternating)
Who experimented with alternating currents of electricity?
In alternating current the flow of electric charge periodically reverses direction. Nikola Tesla was an inventor, mechanical engineer, and electrical engineer. Tesla devised a better system for electrical transmission - the AC system that we use in our homes today. AC offered great advantages over the DC system. By using Tesla's newly developed transformers, AC voltages could be stepped up and transmitted over long distances through thin wires.
