🔍 Key Concepts

• Inductance as a property of coils in AC (alternating current) and DC (direct current) circuits • How a changing current creates a changing magnetic field, and how that field reacts • Difference between opposition to current change vs. opposition to voltage change

💭 Think About

• Think about what happens in a coil when you try to increase or decrease the current quickly—what electrical effect appears? • Is inductance more closely associated with magnetic fields caused by current, or with applied voltage directly? • When current changes, does inductance tend to resist that change or help it happen faster?

✅ Before You Answer

• Be clear that inductance is defined in relation to changing current, not just steady current • Recall that inductors try to keep current flow the same by generating their own induced voltage • Eliminate any options that suggest inductance directly helps or aids changes instead of resisting them
