🔍 Key Concepts

• Inductance and how it resists changes in current • Difference between inductive and capacitive effects in AC circuits • Meaning of reactance versus ordinary resistance

💭 Think About

• In an AC circuit with a coil (inductor), does the opposition come from voltage leading or lagging current, or from energy stored in an electric field? • Which term is specifically used for opposition caused by a coil, and which one is for opposition caused by a capacitor? • Among the choices, which are standard electrical engineering terms you’ve seen in basic AC theory?

✅ Before You Answer

• Confirm which choice refers to opposition due specifically to inductance (a coil). • Eliminate any option that clearly refers to capacitance (capacitor behavior). • Check which terms are commonly defined in AC theory textbooks as forms of reactance vs. non-standard wording.
