I-ohms-resistance

Increasing voltage increases current.Increasing resistance decreases current.

Decreasing voltage decreases current.

Decreasing resistance increases current.

What is Ohm's Law?

## Ohm's Law Variables:

## Current Current is moving electrons, moving charge. Increasing current causes more electricity to move through a device. Increasing electricity through a device causes it to work faster (in a motor) or be brighter (in a lightbulb). | ## Voltage Voltage is electrical potential: how much work a battery can do. Voltage is linked to energy: 1 volt of voltage = 1 joule per coulomb of charge. To increase voltage you could use a stronger battery OR add batteries. | ## Resistance Resistance slows down current. Think of resistance like a dam holding back water. Adding devices in a circuit increases resistance. |

## Current

Current is moving electrons, moving charge. Increasing current causes more electricity to move through a device. Increasing electricity through a device causes it to work faster (in a motor) or be brighter (in a lightbulb).

## Voltage

Voltage is electrical potential: how much work a battery can do. Voltage is linked to energy: 1 volt of voltage = 1 joule per coulomb of charge. To increase voltage you could use a stronger battery OR add batteries.

Just to give you a little more understanding....

## Series and Parallel Circuits are fun too!

## Series Circuit

Series Circuits have all only one path for the electricity to flow. If any part of the series circuit is broken, the circuit fails. If either light is unscrewed both light will turn off. If there are two lightbulbs in a series circuit, they both depend on the other.

## Parallel Circuit

Parallel circuits have multiple paths for the electricity to flow. The branches (paths) of a parallel circuit are independent. If either light is unscrewed, the other will remain on.

Parallel and Series circuits

## Objective

On this page, it concludes understanding the meaning of Ohm's Law. There are many things that we are going to examine, but the main things we are going to cover is variables dealing with Ohm's law. It also looks over series circuit and parallel circuit. I really hope you enjoy this page. :)
