• The seven SI base units, which are comprised of:
  • Length - meter (m)
  • Time - second (s)
  • Amount of substance - mole (mole)
  • Electric current - ampere (A)
  • Temperature - kelvin (K)
  • Luminous intensity - candela (cd)
  • Mass - kilogram (kg)
• Ohm (Ω) is the SI unit of Electric Resistance.
• Volt (V) is the SI unit of Electric Potential.
• Siemens (S) is the SI unit of Electrical conductance.
