Electrical potential difference
The amount of electric power that pushes electricity through a wire, measured in volts.
用法模式：
[voltage] of [something]
常见错误：
Learners sometimes confuse 'voltage' with 'current'. Voltage is the force that pushes electricity, while current is the movement of electric charge.
近义词
electric potential (More formal and scientific term, used in physics contexts.)

potential difference (Physics term emphasizing the difference between two points.)
反义词
current (In electricity, current refers to the flow of charge, not the potential difference.)
