🔍 Key Concepts

• Inductance is related to magnetic fields and changing current in a coil of wire • Each electrical quantity has a standard SI unit (for example, resistance, capacitance, charge) • Match each choice with the electrical property it usually measures

💭 Think About

• Which electrical quantity deals with how strongly a coil opposes changes in current due to its magnetic field? • Can you recall the SI unit for resistance, and for capacitance, and for electric charge? That will help you eliminate some options. • After eliminating the known units, which remaining option is associated with coils and magnetic energy storage?

✅ Before You Answer

• Identify which option is the unit of resistance and cross it out. • Identify which option is the unit of capacitance and cross it out. • Identify which option is the unit of electric charge and cross it out; the remaining one is the unit for inductance.
