The use of resistors in electrical devices is not a new concept. Resistors have been used for the longest time now in electric circuits to obtain a number of effects. Firstly, there would be no heating using electric appliances without the use of resistors. Heaters, stoves and electric bulbs all rely on the power of resistors to generate heat by converting electric energy. The resultant energy is the harnessed and channeled for use in heating our homes, in heating devices as well as heating industrial premises.

The use of resistors is not only limited to heating. Resistors are known and have thus been used as daisy chains in dividing voltage passing through electric circuits. There are certain appliances whose power intake is lower than that generated at the mains. Such appliances would blow up in an instant when the voltage passing through them is not regulated. The regulation of this voltage requires that there is some resistance applied in the path of the voltage. Since voltage through a component is a product of both electric currency and resistance, the implication for this is that the resistance applied will be directly proportional to the amount of voltage that flows through a component in a circuit.

More than this, there are devices, electronic for that matter, that would never be able to function in a circuit devoid of some electrical resistance. Such devices cannot operate in conditions of too high or too low electric currencies. Higher currency destroys them. Low currency, on the other hand, is not sufficient to power them. To ensure that a right balance of the current going through them is maintained, such devices require the use of resistors. The resistors when used in this way offer optimal currencies for the working of those devises. Some of the commonest devices that exhibit such characteristics include the LED lights and transistors.

Finally, custom resistor can be used in devices that need timing for them to operate. These devices make use of electric current to generate charge that has to be stored in certain charge reservoirs. These charge reservoirs have to be filled with electric charge before they can complete a timing cycle. The commonest reservoirs are the capacitors. By making use of resistors and determining the capacity of those capacity, electricity flow to those capacitors can be regulated by use of resistors. The time taken to fill the capacitor will determine the timing mechanism.
