One can interpret electric voltage as a difference in height by drawing an analogy to gravitational potential energy. In a gravitational field, an object at a higher height has more potential energy than an object at a lower height. Similarly, in an electric field, a charge at a higher voltage has more potential energy than a charge at a lower voltage. This analogy helps in understanding how electric voltage represents the potential energy difference between two points in an electric circuit. **
