# Ohm's Law

### By: Rosa Ruiz

What is Ohm's Law?

## How to solve!

If you know two of the three variables you should be able to solve for the third.

When using Ohm's law always use the 3 step form

-1. Write the equation

-2. Replace the know values

-3. Solve the problem

## Ohm's Law

defines the relationship between voltage, current and resistance.

These basic electrical units apply to direct current, or alternating current.

Ohm’s Law is the foundation of electronics and electricity.

This formula is used extensively by electricians.

Without a thorough understanding of “Ohm’s Law” an electrician can not design or troubleshoot even the simplest of electronic or electrical circuits.

Ohm established in the late 1820’s that if a voltage was applied to a resistance then “current would flow and then power would be consumed”.
