Resistors

Resistors are passive electronic components that limit or control the flow of electrical current in a circuit. Their ability to slow or impede electrical current is called resistance, which is measured in ohms (Ω). Resistors are designed with a known value of resistance and leverage this resistance in circuits to protect other compoents, divide current/voltage, and adjust signals.

Resistors are two-terminal devices that are typically made of materials with high resistance, such as carbon or metal. When a voltage is applied to a resistor, it resists the flow of electrical current, causing a voltage drop across the resistor. This voltage drop is proportional to the amount of current flowing through the resistor and the resistance value of the resistor, according to Ohm's law.

Resistors are included in circuit designs to reduce current flow, adjust signal levels, and bias active elements. They are also used for current sensing, load balancing, and many other tasks where precise control of current or voltage is necessary.
