The voltage loss across part of a circuit due to impedance is called

• A. Potential Difference
• B. Voltage Rise
• C. Voltage Drop
• D. Power Loss

Answer: (C)

Voltage drop is the decrease in electrical potential as current passes through a circuit element with impedance. When current flows through a resistor or reactive component, energy is dissipated or stored, so the voltage across that element is lower on the output side—the difference is the drop. In a loop, that drop adds up so the source voltage equals the sum of all drops. The general term for any voltage between two points is potential difference, but the specific loss across a circuit element due to impedance is called a voltage drop. Voltage rise would be an increase in potential (typically at a source), and power loss refers to energy conversion rate, not the voltage difference itself.
