What is a resistor ?
Resistor limits electric flow, like a faucet controls water. It resists current.
Resistors reduce current, controlling voltage. Think of them as traffic regulators for electrons.
How Resistors Work
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
Resistor obeys Ohm's Law: V = I * R. Voltage, current, and resistance interplay.
Ohm’s Law Connection
Power ratings indicate how much heat a resistor can handle. Don't exceed limits.
Found in every electronic device, resistors play crucial roles in circuits for stability.
