DESIGNING OF MOTOR GENERATOR

SIMPLE EXPERIMENT:
DESIGNING OF MOTOR GENERATOR

Try this experiment to see the relationship between the motor and generator. You need two small electric motors from toy cars for children: Connect one motor with a battery, the motor will rotate. Turn off the first motor bike while you connect it to the second. This must be connected with a light bulb. If you turn on the switch, the first motor will make a second motor works like a dynamo. Currents generated by dynamo lit a lamp.

POWER GENERATION
You've seen how electric currents can produce movement and how the electric motor also produces an electric current from the motion. Source of national electricity generated or "raised" by rotating the magnets at high speed inside the coil of wire.

MAKING ELECTRICITY
The diagram below shows how the spinning motion of a windmill can be turned into electricity to power a alampu bol. "Generator" or dynamo like the reverse of the motor. As the windmill rotates, the mill is making a wire coil rotates between the two magnets. Electric current generated and used to light bulbs. Dinamo like this can be used to power bicycle lights. In this case the coil is driven by the wheels when turning. The main power source in your house was raised in a power station in the same way of working. However, the powerhouse magnetlah that rotates in the coil of wire. Moving the magnet in this way can generate a number of very large currents.

ELECTRICITY GENERATION
Listiik power generating electricity with large scale for homes and industries. Giant turbines rotate the magnets in the wire coil to generate electrical current. A turbine is like a series of big wheels or fan. Turbine can be rotated by steam or water. Steam to drive turbines can be produced using coal or oil to boil water. Or it could be the driving energy comes from nuclear reactions. Once electricity has been generated electricity must be transmitted to the entire city where electricity is needed. The following diagram shows how the turbine is designed to be
spin.

Grid
Electric current is transferred from power plants with large cables. Most of these cables are buried below ground and partially mounted high above the ground with a metal structure that towers to support it. System towers and wires connecting all power plants in a country in one vast network of networks called lisirik. Diagram showing how electricity came to your city from the electricity network. Electric power cables brought this cable is very large. Thus, before the current can be used safely in your home, this power should be reduced or the "transformasika" helper station / substation. Electricity network allows power to be transferred from one other area of the area for residential purposes. If the local power station in no way, electrical current from another power station is channeled through wires in the electrical network. This allows the permanent availability of electricity in areas with damaged power plant. In this way cut off of power lines can often be avoided.
