What?
Sometimes look for a way to control or reduce the flow stream of a particular source of energy .... For example, a battery ....
Wire connector battery pip large water .. And electricity is water inside .. And you do not want to use this quantity of water .. For this we use either water or a tube fitted with a smaller size or any way to reduce the amount of water flowing ...
Resistance .. Do the same thing for the power supply .. They resist the flow of current in a circuit .. Connector is not good for the stream ..
Measured the resistance unit called Ohms ..
.. Ohm The letter Grecian
Many electronic parts are sensitive to electrical currents might damage the high and the only way to protect them is by using the resistors, the resistance is working on determining the severity of the current that passes the more the resistance value of said intensity of the current passing through it. The resistors used to regulate the currents passing in the different parts of the Service ...
How it works??
Resistance to allow operation of high power Valuate little, plastic, for example, air resistance and high current does not apply where metals such as gold, silver and copper resistance is low, it allows operation of power easily. If Valma's good resistance to be small and vice verse. Therefore, if you look to find the wire consisted of a metal part of the current and allows the operation of this section is covered with material such as plastics are high-resistance does not apply where the tide. The resistance of all kinds Fmquaomadtha medium, it allows the passage of some electrical
