Which statements about voltage are correct?

• A. It Is Electrical Pressure
• B. It May Be AC Or DC
• C. Both A And B
• D. Neither A Nor B

Answer: (C)

Voltage is the electrical potential difference that pushes current through a circuit. Describing it as electrical pressure helps you picture how a higher potential at one point compared to another pushes charges to move, though the precise idea is energy per unit charge. Voltage can come from different sources and take different forms: DC is steady, like a battery, while AC varies with time, such as the power from a wall outlet. Because both steady (DC) and time-varying (AC) voltages exist in circuits, both statements are true: it’s like electrical pressure, and it can be AC or DC.
