# Resistors

### By Jose Araujo

## Objective

Resistors act to reduce current flow, and, at the same time They act to lower voltage levels within circuits. The current through a resistor is in direct porportion to the voltage across the resistor's terminals.The Color Codes on the resistors determine What The Value Of The Resistor Is going to be. There value is measured in ohms.

What is a Resistor?

## Interesting Facts

-A resistor represents a given amount of resistance in a circuit.

-Resistance is a measure of how the flow of electric current is opposed or "resisted."

-It is defined by Ohm's law which says the resistance equals the voltage divided by the current.

-The Ohm is often represented by the omega symbol: Ω.

-It is defined by Ohm's law which says the resistance equals the voltage divided by the current.

-Resistance = voltage/current

-The Ohm is often represented by the omega symbol: Ω.

## What Are Resistors Used For ?

Resistors are electrical components that help control the amount of current in a circuit. The most common types are regular or ohmic ones, where the higher the resistance is, the less current there is that is available for a given voltage.
