A resistor is a passive two-pin electrical element whose purpose is to create electrical resistance in a circuit. In electronic circuits, resistors are mainly used to reduce current flow, adjust signal levels, and split voltages. Resistors can also be responsible for the polarization of active elements and the termination of transmission lines.
Generally speaking, resistors are most often used to limit the flow of current. The role of the resistor is to take power and convert it into heat. The whole process uses Ohm's law. Some voltage is deposited on the resistor. The power itself is generated when electric current flows through the element and there is voltage at the terminals. There are many different types of resistors, but for standard products, the principle of operation is more or less the same.
Resistors are available with a wide range of resistance, spanning twelve orders of magnitude, and a wide range of wattages. Depending on the purpose, choose low-power resistors (0.125 W to 0.5 W) or high-power resistors for yourself and your project. There are also heating elements (1000W and more).
