Resistors

Resistors limit the flow of electric current in a circuit. They are used to protect sensitive components from receiving too much current and to divide voltages. Resistors come in various types, including fixed, variable, and special types like thermistors and photoresistors. Their resistance value is measured in ohms (Ω), and they are often color-coded to indicate their resistance value.

In addition to basic current-limiting applications, resistors are crucial in creating voltage dividers, which split voltages into smaller, desired levels. They also play a role in filtering applications, where they work with capacitors and inductors to remove unwanted frequencies from signals. Resistors are fundamental components in electronic design, ensuring that circuits operate safely and efficiently.
