Electrical potential is a fundamental concept in the field of electromagnetism. It refers to the physical quantity used to measure the amount of electrical energy stored in a system. There are several synonyms for electrical potential, including voltage, electric potential difference, and potential drop. Voltage measures the electric potential difference between two points in a circuit or system. Potential difference is the difference in electrical potential between two points. Potential drop refers to a decrease in electrical potential as current passes through a resistor. These terms are often used interchangeably, but they all refer to the same fundamental concept of electrical potential.
