Contains four impedances that form a square?

• A. Bridge Circuits
• B. Complex Circuits
• C. Delta Network
• D. Three-Phase Circuit

Answer: (A)

Recognizing a configuration with four impedances arranged in a square is characteristic of a bridge circuit, such as a Wheatstone bridge. In this setup, each side of the square is an impedance, and a detector or source connects across one diagonal. When the impedance ratios on opposite sides are equal, the bridge is balanced and no current flows through the detector, enabling precise comparison or measurement of an unknown impedance. A Delta Network uses only three impedances forming a triangle, not four in a square. A Three-Phase Circuit refers to three-phase power systems and isn’t defined by a square of four impedances. A Complex Circuit is a broad term that doesn’t specify this square arrangement.
