What equations are used to calculate potential difference, current, and resistance from the other two quantities?

  • Potential difference: V=IRV = IR
  • Current: I=VRI = \frac{V}{R}
  • Resistance: R=VIR = \frac{V}{I}

What standard units are used for potential difference, current, and resistance?

  • Potential difference: volts (V)
