Question

Does the in-phase relationship of a pure resistor hold for any combination of a pure resistor, a pure inductor, and a pure capacitor?

Options

• Yes; the phase angle is always zero \[0^\circ\].

• Yes; current and voltage are always in phase.

• No; current is NOT in phase with voltage.

• Yes; the phasors always point in the same direction.

Answer 1

The in-phase relationship described for a pure resistor does not hold for combinations of these elements. Phasors provide a way to represent the resulting phase difference.
