What is the symbol used to represent impedance in electrical equations?

• A. Z
• B. R
• C. V
• D. I

Answer: (A)

The symbol used to represent impedance in electrical equations is Z. Impedance is a complex quantity that combines resistance and reactance in an AC (alternating current) circuit. It is measured in ohms (Ω), similar to resistance, but it also accounts for the phase difference between voltage and current due to inductive and capacitive elements in the circuit. In electrical engineering, Z is crucial when analyzing circuits to understand how voltage and current behave in relation to each other. The resistance (R) only considers the resistive elements, while Z encompasses both resistive and reactive effects, making it essential for AC circuit analysis. Understanding impedance is fundamental in designing circuits, especially when dealing with alternating current loads, ensuring that systems work efficiently and effectively.
