  • Electric potential equation

  • Units of electric potential

    volts (V)

  • SI derived units for electric potential

    joules per coulomb (J/C)

    joules per coulomb (J/C)

  • Electric potential true equation

  • Electricity basic equations

    Take Coulomb's Law and manipulate it. From left to right, multiply by r; from top to bottom, divide by q.

    from + to –

    from – to +

  • Charges, if allowed, will move spontaneously in whatever direction results in a _____. For a positive test charge, this means moving from a position of _____ electric potential to a position of _____ electric potential.
