đ Key Concepts
⢠Basic electrical units and what they measure: voltage, current, resistance, energy, charge, inductance
⢠Common SI units in electricity: volt, ampere, ohm, joule, coulomb, henry
⢠Relationship between inductance and a coil in a circuit (how it resists change in current)
đ Think About
⢠First, match each choice to what physical quantity it normally measures. For example, which one is energy, which is electric charge, which is resistance, etc.?
⢠Think about where inductors appear in DC/AC circuits and what symbol (L) they use. What SI unit is paired with that symbol in textbooks or circuit diagrams?
⢠Eliminate any options that you know belong to other quantities, then see which remaining unit is associated with inductance.

Before You Answer
⢠Be sure you know: Joule = unit of energy, Coulomb = unit of electric charge, Ohm = unit of electrical resistance
⢠Confirm which SI unit is specifically defined for inductance in basic electronics references.
⢠Before choosing, double-check that the unit you pick is NOT already âtakenâ by a more basic quantity like charge, energy, or resistance.
