What is an alternator

An alternator is an electric generator which produces alternating current through mechanical means.

What is imperialism

Imperialism is basically the formation of an empire.

It is more specificially the creation and/or maintenance of an unequal economic, cultural, and territorial relationships, usually between states and often in the form of an empire, based on domination and subordination.

It occurs when one country takes control (sometimes aggressive, sometimes passive) over a country. This occurred widely throughout history as the conquest of weaker cultures by cultures that were more powerful or more technologically advanced. Military imperialism generally ceased following the two World Wars, the formation of the United Nations, and the eventual demise of the Soviet Union. So-called "economic imperialism" is a separate and continuing but equally contentious policy.

Imperialism, as defined by Dictionary of Human Geography, is "the creation and/or maintenance of an unequal economic, cultural, and territorial relationship, usually between states and often in the form of an empire, based on domination and subordination."
Imperialism refers to a policy of extending the power of country through a military force or through diplomacy.
Imperialism is the hegemony of the colonialism over small countries or nations.

What is a direct current

An electric current flowing in one direction only.

How does a generator produce electricity

. This causes electrons to move through the conductor, which is creates a flow of electricity that we can use for lighting or running our computers.

How does a step up and step down transformer work

A step up transformer has more turns on the secondary (output) coil than the primary (input) coil. A step down transformer has less turns on the secondary (output) coil than the primary (input) coil

How is electrical generator work

A current can be induced by a (moving) magnetic field ...

so you spin a magnet inside a coil of wire and you have a generator.

The process of generating an electric current from the motion of a conductor in a magnetic field is

The process of generating an electric current from the motion of a conductor in a magnetic field is known as induction.

What does a generator do

A generator is a device that converts mechanical energy into electrical energy by electromagnetic induction - it "generates" (or creates) electricity.
A generator is a mechanical device which converts mechanical energy to electrical energy. Generators may be driven by a broad range of sources; steam turbines, electricity, petrol, or oil, natural gas, wind, and even water (hydroelectric).

How did the United States acquire Alaska

Alaska was purchased from Russia for $7,200,000 in 1867.
Bought it from Russia for 7.2 million in 1867

What is US voltage and Ecuador voltage

US Voltage is 120 V @ 60 Hz.
Ecuador Voltage is 120 V @ 60 Hz.

They're compatible, the plugs are also the same.

A device that supplies the mechanical energy to turn the armature of a generator is a

Is a turbine

In what three ways did us supporters of expansion justify increased involvement in world affairs

1. To stop Communism from spreading.

2. To try to bring about world peace.

3. Trade / Economics reasons

Name the essential parts of the motor and generator

Armature, field magnet, slip rings in case of AC generator or split rings in case of DC generator and carbon brushes.

How do generators run

By help of prime mover which supplies the mechanical energy to the shaft of generator(in case of dc generators).

Does a generator produce direct current or alternating current

A generator produces an alternating current, still it gives d.c. output because we use slip-rings at the terminals of actual output of generator.

Moving a magnet in and out of a coil of wire produces a what

An electric current.

What is used to make steam into electrical energy

A turbine.

What is the rules as per transformer work

Transformer works on the principle of Electromagnetic induction.

Is television an electrical or electronic device

electrical and electronic is the same thing

your TV uses electricity

Which marked the end of the us policy of avoiding involvement in the affairs of other countries

World War II

What additional factor will be changed if the direction of a current flow is changed if the direction of a current flow is changed

The voltage

Does a step-up transformer have fewer turns of wire in the primary than in the secondary

Yes, a step-up transformer has fewer turns of wire in the primary than in the secondary.

What does a buck boost transformer do

A buck boost transformer is a type of transformer that is used to make adjustments to the voltage applied to alternating current equipment. These transformers are typically used in back up supplies or in tanning beds.

What term describes a smoothly varying signal produced by continuously changing the voltage or current in a circuit

analog signal

How far can the loop in a galvanometer travel

a full circle

When transformer voltage regulation will be zero it operate at

A transformer will operate with a voltage regulation of zero when it is not supplying a load.

What did Thomas Edison's first generating plant produce

direct current .

Which type of current does a transformer work with

AC (alternating current)
