• ELECTRIC POTENTIAL ENERGY (U)

  → The energy that is needed to move an electric charge against an electric field.
• Symbol: U ; Unit: N•m or J (Joules)

  General Formula: U= kq1q2/r
• ELECTRIC POTENTIAL (V)

  → the amount of work needed to move an electric charge from its reference point to specific point

  on electric field.
• WHEREIN: U = electric potential energy (N•m or J)

  K = Coulomb’s Constant (8.988 x109 Nm2/C2

  q1q2 = charge (C)

  r = distance (m)
• Symbol: V ; Unit: J/C or V (volts)

  General Formula: V=kq/r or V=U/q
• WHEREIN: V = electric potential (J/C or V)

  K = Coulomb’s Constant (8.988 x109 Nm2/C2)

  Q = charge (C)

  r = distance (m)
