What is a resistor ?

Basic Electronics

Resistor limits electric flow, like a faucet controls water. It resists current.

Introduction

arnin.in

Resistors reduce current, controlling voltage. Think of them as traffic regulators for electrons.

How Resistors Work

arnin.in

Different types include fixed (constant value) and variable (adjustable). Each suits specific tasks.

Types of Resistors

Resistor color bands signify values. Decode the bands to reveal the resistance.

Color Code Decoded

The unit of resistance is the ohm (Ω), and the symbol for resistance in equations is "R."

Unit and Symbol

arnin.in

Resistor obeys Ohm's Law: V = I * R. Voltage, current, and resistance interplay.
