Question 1 of 27070

In an alternating current circuit, what factor of a circuit will cause the inductive reactance to vary?

🔍 Key Concepts

• Inductive reactance (XL) and how it depends on circuit properties • The formula for inductive reactance in an AC circuit • Difference between quantities that are set by the source (like voltage and frequency) vs. what results from the circuit (like current)

💭 Think About

• Recall or look up the basic formula for inductive reactance and identify which variable(s) appear in it. • Ask yourself: if I keep the inductor the same and change each option (resistance, frequency, voltage, current) one at a time, which change will directly change the value of XL in that formula? • Consider which quantity is tied to how rapidly the current is changing direction in an AC system.

✅ Before You Answer

• Write down the formula for inductive reactance, XL, and underline the variable that can change in a given AC system. • Verify which of the answer choices is directly in that formula, not just indirectly related through Ohm’s Law. • Make sure you are not confusing inductive reactance (XL) with impedance (Z) or simple resistance (R).
