Question 1 of 27070

In an AC circuit, a series inductance acting alone:

🔍 Key Concepts

• AC inductive reactance (XL) and how it affects phase between voltage and current • Phase relationship rule for pure inductance in AC circuits (no resistance, no capacitance) • Difference between lagging and leading current relative to voltage

💭 Think About

• Picture a circuit that has only an inductor connected to an AC source—no resistor, no capacitor. In that ideal case, which quantity (voltage or current) reaches its peak first? • Recall the memory aid used in basic AC theory for inductive and capacitive circuits (something like: "ELI" and "ICE"). What does that tell you about which one leads or lags? • If the circuit is purely inductive (not a mix of R and L), is the phase shift usually 90 degrees or something less like 45 degrees?

✅ Before You Answer

• Verify what pure inductance (L alone) does in an AC circuit, without any resistance or capacitance present • Confirm whether the phase angle for a purely inductive circuit is exactly 90° or some other value • Double-check which quantity (current or voltage) is said to lag the other in a purely inductive AC circuit, using your ELI/ICE mnemonic or textbook diagram
