🔍 Key Concepts

• AC circuits with mixed loads (resistance + inductance) • How purely resistive and purely inductive circuits each affect phase between current and voltage • Remembering which one makes current lead or lag

💭 Think About

• First, recall the phase relationship in a purely resistive AC circuit: how are current and voltage aligned? • Next, recall what happens in a purely inductive circuit: does current lead or lag voltage? • Now, if a circuit has both resistance and inductance, would you expect the behavior to be exactly like a pure resistor, exactly like a pure inductor, or somewhere in between?

✅ Before You Answer

• Be clear on which component (inductor or resistor) is responsible for any phase shift. • Verify whether a purely resistive circuit can cause current to lead or lag (or neither). • Ask yourself if adding resistance to an inductive circuit can completely cancel the inductive phase effect or only reduce it.
