How to wire a resistor

How to wire a resistor

it has two terminals. it is not sensitive to polarity. so connect one terminal to a voltage and the other terminal to another voltage. the current through the resistor will be the difference between the voltages divided by the resistance.

Hanging a terminal involves connecting a lead wire using solder or other electrical connection means.

It depends entirely on what you want the resistance to do. but here are some ideas that might be useful:

Resistors do not have polarization. like incandescent bulbs, they can not be wired upside down.

Often, the resistors are wired in a circuit to limit the voltage across a load. for this application, the resistor is wired in series with the load.

other times, a resistor is used to limit the current through a load. for this application, wire the resistor in parallel with the load. for all intentions and ends resistances have no polarization. they can be wired backwards or forwards (which are the same).

With this in mind, keep a few things in mind when wiring a resistor:

the amount of energy passing through the resistor should be moderate as it can cause overheating. a resistor can be connected in series or in parallel as needed.

it is connected in series when the resistance has to be stacked or added. the current does not divide.

it is usually connected in parallel when the current must be divided, that is to say to control the current flowing in another device connected in parallel.

To a certain extent, it depends on the type of resistance, but it does not matter in general (the resistors, unlike transistors, diodes and some capacitors, do not usually worry about the direction of the current flowing through them). you wire each terminal to one of the desired locations. you will need to pay attention to the amount of power that the resistor will dissipate if it exceeds a few mw if the resistance is small (1/4 w, 1/8 w etc.). this is obtained by multiplying the square of the current through the resistance by the resistance (i ^ 2 * r)

if the resistance is not a standard resistor (for example, the version with colored bands), then it depends on functionality.
