The unit of electric potential difference is _________.
Volt
Ampere
Ohm
Watt
Volt
The unit of electric potential difference (commonly known as voltage) is the volt (V), named in honor of the Italian physicist Alessandro Volta. One volt is defined as the potential difference between two points when one joule of work is done to move a charge of one coulomb between them.

Think of electric potential difference like water pressure in a plumbing system: the voltage is the pressure pushing water (electrons) through the pipes.
V = W / Q (Voltage equals Work divided by Charge)
V=QWтАЛ тАФ Electric potential difference in terms of work and charge
V=I├ЧR тАФ Ohm's Law relationship for voltage
Electric potential difference represents the energy required to move a unit electrical charge between two points within an electric field. It acts as the driving force or pressure that pushes free electrons through a conductor, creating an electric current when a closed circuit is established.
The SI unit of electric potential difference is the volt (V).
It is equivalent to one joule per coulomb (1┬аJ/C).
A voltmeter is always connected in parallel in a circuit to measure potential difference.
Measuring electrical potential in domestic power supplies
Calculating voltage drops across components in electronic circuits
Option B (Ampere) is the SI unit of electric current.
Option C (Ohm) is the SI unit of electrical resistance.
Option D (Watt) is the SI unit of electric power.
A is correct тАФ The SI unit of electric potential difference is the volt.
Make sure not to confuse electrical units: remember that Current flows in Amperes, Resistance opposes in Ohms, and Potential Difference pushes in Volts.
