🔍 Key Concepts

• Inductance vs. inductive reactance in AC circuits • Standard electrical units: ohm, mho/siemens, henry, farad • How resistance and reactance are both expressed in circuit calculations

💭 Think About

• Which electrical quantity shares the same unit as resistance, since both oppose current flow? • What is the usual unit for inductance itself, and is that the same thing as inductive reactance? • Which unit is normally used for capacitance, and is that related to inductive reactance?

✅ Before You Answer

• Remember that inductance and inductive reactance are different concepts with different units • Check which unit is used in Ohm’s Law-type calculations for AC circuits (includes reactance and impedance) • Eliminate units that are clearly associated with capacitance or with conductance rather than opposition to current
