Electrical potential difference
The amount of electric power that pushes electricity through a wire, measured in volts.
รูปแบบการใช้:
[voltage] of [something]
ข้อผิดพลาดที่พบบ่อย:
Learners sometimes confuse 'voltage' with 'current'. Voltage is the force that pushes electricity, while current is the movement of electric charge.

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