PHYS 1041 Lecture Notes - Electric Field, Elementary Charge, Electric Potential
Document Summary
Electric charge: electric charge: property of electrons and protons positive attracts negative positive repulses positive negative repulses negative: s. i. unit for electric charge is a coulomb, abbreviated c. 1 proton charge: +1. 60 x 10-19c strength of an electrical force affected by the charge and distance from the charge. To consider the force that a charge 1 (q1) exerts on charge 2 (q2) : F = where k is a constant, equal to 9. 0 x 109nm2/c2 and r is the distance between the charges and r(hat) indicates the direction only (has no numerical value) E = for a given charge placed in the electric field. Electric field: electric field: electric force per unit charge: when e= electric field, when f = electric force, when q= unit charge then. Voltage: electric potential difference consider electric energy per unit charge. V holds true when electric field is constant in a certain.
