Electric Potential

Electric Potential

1. Electric Potential Energy

   • Energy Stored in an Electric Field
     • work done by gravity
   • U= k(q1q2) / r
     • EQUATION TO USE
   • WHAT IS IT?

2. Electric Potential

   • Work done by the forces
     • divided by the charge of particles
     • WHAT IS IT?
   • V= w/q
     • EQUATION TO USE
     • UNIT USED
       • J/C= Volt
   • DIFFERENT FROM
     • AV=-Ed

3. CALCULATED BY

   • voltmeter

4. UNIT USED

   • joule per coulomb(J/C)

5. NEGATIVE

   • MEANS
     • GAIN OF ELECTRONS

6. POSITIVE

   • MEANS
     • LOSS OF ELECTRONS

7. CAN BE

8. WHAT DOES IT PRODUCE ?

   • when at rest
     • Produces electric field
   • when in motion
     • Produces magnetic field

9. Equipotential surface are the points in an electric field
