When a current flows through a conductor in a magnetic field, it experiences a force. The relation between the directions of the current, field and force can be. When a current flows through a conductor in a magnetic field, it experiences a force. The relation between the directions of the current, field and force can be. An AC generator is an electrical machine which converts mechanical energy into electrical energy. It uses faradays law of electromagnetic.

Simple ac generator the coil is in the position shown in the diagram, side 2 is moving down and side 1 is moving up. While DC motors require the use of brushes to make electrical contact with moving coils of wire, AC motors do not.

AC (Alternating Current) Generators

This relative simplicity translates into greater reliability and lower cost of manufacture. But what else is AC good for?

Surely there must be more to it than design details of generators and motors! There is an effect of electromagnetism known as simple ac generator inductionwhereby two or more coils of wire placed so that the changing magnetic field created by one induces a voltage in the other.

If we have two mutually inductive coils and we energize one coil simple ac generator AC, we will create an AC voltage in the other coil.

The coil gets slightly warm. What simple ac generator we instead connect a light bulb between the ends of the coil? A light bulb is really just a piece of thin wire. The charges of the light bulb's filament will be pushed along.

When the charges within the copper wire pass into the thin light bulb filament, their speed greatly increases.

When the charges leave the filament and move back into the larger copper wire, they slow down again. Inside the narrow filament, the fast-moving charges heat the metal by a sort of electrical simple ac generator.

  • What is Alternating Current (AC)?

The metal filament gets so hot that it glows. The moving charges also heat the wires of the generator a bit, but since the generator wires are so much thicker, and since the bulb's thin filament is slowing the simple ac generator throughout the entire coil, almost all of the heating takes place simple ac generator the light bulb filament.

So, just connect a light bulb to a coil of wire, place a short powerful magnet in the coil, then flip the magnet fast. The faster you spin the magnet, the higher the voltage pump-force becomes, and the brighter the light bulb lights up.

AC (Alternating Current) Generators

The more powerful your magnet, the higher the voltage and the brighter the bulb. And the more circles simple ac generator wire in your coil, the higher the voltage and the brighter the bulb. In theory you should be able to light up a normal 3V flashlight bulb, but only if you can spin your simple ac generator inhumanly fast.

While still spinning the magnet, have a friend touch the wires together so the bulb lights up again.

AC generators

Is the nail still as easy to spin? Keep spinning the magnet while your friend connects and disconnects the simple ac generator. Do you feel any differences in how hard you must spin the nail?

Also try spinning the magnets while your friend connects the generator wires directly together with no bulb connected.

Generators & Dynamos

When you crank the generator and make the lightbulb simple ac generator on, you are working against electrical friction in order to create the heat and light.

You can FEEL the work you perform, because whenever you connect the bulb, it suddenly gets harder to crank the generator. When you disconnect the bulb, it gets easier. Think of it like this.

If you rub your hands together lightly, the skin stays cool, but if you rub your hands together hard, your skin gets hot. It takes more effort to simple ac generator skin hard so that it heats up; it takes work.
