🔍 Key Concepts

• Relationship between inductive reactance (XL), frequency (f), and inductance (L) in AC circuits • Difference between inductive reactance (XL) and capacitive reactance (XC) formulas • How reactance changes when frequency increases for an inductor vs. a capacitor

💭 Think About

• Which formula shows inductive reactance increasing as frequency increases? • Which option is actually the formula for capacitive reactance, and not inductive reactance? • Look at the units: if L is in henrys and f is in hertz, which formula gives you ohms for reactance?

✅ Before You Answer

• Identify which formulas contain L (inductance) versus C (capacitance) • Check that the formula for inductive reactance has XL directly proportional to both f and L • Eliminate any formulas that clearly belong to impedance combinations rather than pure inductive reactance
