Electrical Potential Difference

The work done to move a positive test change from one location to another.

1. V=W/q

2. E=v/d

 

Interaction between charges

• Electric Field is the space around an electrical charge just like a gravitational field is the space around a mass.  Clulomb´s law- Gives the electric force between two point charges 

F=K qi-q2/r2

Formulas of Physics

 Celsius to Fahrenheit= (C°)x9/5 +32

Fahrenheit to Celsius= [(F°)-32°]x5/9

Celsius to Kelvin= (C°)+273

Kelvin to Celsius= (k)-273
