Q

A capacitive AC circuit has fixed capacitors connected in series. If the line voltage remains constant, what factor can allow the capacitive reactance of the circuit to be varied?

🔍 Key Concepts

• Capacitive reactance and its basic formula • What quantities are fixed in this question (line voltage and fixed capacitors) • Which electrical quantity directly changes reactance in an AC capacitive circuit

💭 Think About

• Write down the formula for capacitive reactance and identify which variables are in it • Decide which of the answer choices appears in, or directly affects, that formula • Think about whether changing the physical order or polarity of ideal capacitors in series will change the total reactance

✅ Before You Answer

• Confirm the standard formula for capacitive reactance (Xc) • Verify that the capacitors are described as fixed, so their values do not change • Check which option changes a variable in the Xc formula without changing the given line voltage or the fixed capacitor values
