Choosing the Right Resistor

Dated:2016-08-04      Popularity:1252


A resistor is a component of a circuit that resists the flow of electrical current. It has two terminals across which electricity must pass, and it is designed to drop the voltage of the current as it flows from one terminal to the other. Resistors are primarily used to create and maintain safe currents within electrical components. It plays an important role in PCB function, so how to choose a right resistor is extremely vital to every designer or manufacturer.

Suppose you need a 200 Ohm resistor, but there are several different types of resistors. Well, the only thing you need to be aware of is the wattage rating of the component. How much effect can the resistor handle? So you need to figure out how much effect that will be dissipated in your resistor. To find this you should learn how to calculate power. Usually, most resistors handle from 250 mw and up, so it will be easy to find a suitable resistor.
