Selection of resistors
A resistor is an electrical device widely used in electronics, now in order to transform electrical energy into thermal energy through the joule effect, sometimes in order to limit electric current in a circuit.
Resistors are components that are intended to provide an opposition to the passage of electrical current through your stuff. The opposition that we call electrical impedance or resistance, which has as a unit ohm. Cause a voltage drop in some part of an electrical circuit, but never cause electrical current outages, although the current limit. This means that the electric current that enters a terminal resistor will be exactly the same out the other end, but there is a power failure. Utilizing addition, you can use the resistors to control the electric current on the desired components.
