If the voltage causes electrons to flow away from the generating source, the voltage is ________.

• A. Positive
• B. Neutral
• C. Negative
• D. AC

Answer: (A)

Voltage is the electrical pressure that pushes charges through a circuit. If the generating source causes electrons to flow away from it into the rest of the circuit, that means the source is delivering energy and has its output at a higher potential relative to the return path. In circuit terminology, that situation is described as a positive voltage. The idea is that the source’s outward push defines a positive potential difference, so current can flow through the circuit from the high-potential terminal to the lower-potential load. A neutral voltage would be no driving pressure, and alternating current would involve a reversal of polarity over time. Negative voltage would imply the source would pull current back or push electrons inward rather than outward.
