🔍 Key Concepts

• Difference between inductive reactance (XL) and capacitive reactance (XC) in AC circuits • How reactances combine when inductance and capacitance are in series in a single-frequency AC circuit • The idea of net reactance (whether the circuit behaves more inductive or more capacitive)

💭 Think About

• Ask yourself: when inductive and capacitive reactances are in series at the same frequency, do you simply add their values, or do you consider their opposite effects? • Think about the sign convention: if inductive reactance is treated as positive, how is capacitive reactance treated when finding the net reactance? • After finding the net reactance, which answer choice matches the magnitude and makes sense physically for a circuit with XL = 40 Ω and XC = 30 Ω?

✅ Before You Answer

• Be sure you are combining 40 Ω and 30 Ω using the correct operation (not blindly adding them). • Confirm whether you should report the magnitude only or include the type (inductive or capacitive) when matching to the multiple-choice answers. • Double-check that the result you compute exactly matches one of the given options; if it doesn’t, re-check your operation between XL and XC.
