PHYS 1510 Chapter Notes - Chapter 16: Electric Potential Energy, Electrostatic Precipitator, Electronvolt
Document Summary
Electric potential is the electric potential energy per unit charge. , where wf is the work non-conservative force. A constant electric field is a field in which the charge moves parallel to where e is the magnitude of the electric field and d is the the charged plates. For positive charges in an electric field, the electric potential energy (which has a lot in common with gravitational energy already) acts very much like gravitational energy. However, epe can have both (+) and (-) values while gravity only has a (+) value. Pe=q v , where v is the electric potential. The electric potential difference is calculating is the work (per unit charge) that would have to be done to move a charge from point a to b in an electric field. This has si units of j/c or volts. To calculate electric potential difference, this equation may be applied: This is only applicable to systems with a constant electric field!
