Extra exam question E5C08
Subelement E5, ELECTRICAL PRINCIPLES· Group E5C
What coordinate system is often used to display the phase angle of a circuit containing resistance, inductive, and/or capacitive reactance?
- A.Maidenhead grid
- B.Faraday grid
- C.Elliptical coordinates
- D.Polar coordinates (correct answer)
WhyPolar coordinates are often used to display the phase angle of a circuit containing resistance and inductive or capacitive reactance. Polar coordinates, which pair a magnitude with a phase angle, are the coordinate system commonly used to display the phase angle of a circuit containing resistance and inductive or capacitive reactance together, answer D. Maidenhead and Faraday grids are unrelated systems (Maidenhead locates geographic position, and "Faraday grid" isn't a real coordinate system), and elliptical coordinates aren't the standard tool for this purpose either.
