What is the SI unit of electric potential?
Watt
Volt
Ampere
Ohm
Volt
The SI unit of electric potential and electric potential difference is the volt (V), named in honor of the Italian physicist Alessandro Volta. It measures the potential energy per unit charge at a given point in an electric field.
The SI unit of electric potential and electric potential difference is the volt (V), named in honor of the Italian physicist Alessandro Volta. It measures the potential energy per unit charge at a given point in an electric field.
Electric potential is like water pressure in a pipe; just as high water pressure pushes water forcefully through a system, high voltage (electric potential) pushes electrical charges through a circuit.
V for Volt, V for Voltage (Potential).
V=QWтАЛ тАФ Electric potential equals work done per unit charge
1┬аV=1┬аJ/C тАФ One volt is equal to one joule per coulomb
Electric potential is defined as the work done in bringing a unit positive test charge from infinity to a point in an electric field. The governing relation is V=QWтАЛ, where V is electric potential, W is work done, and Q is the electric charge.
Named after Alessandro Volta, the inventor of the early chemical battery.
It is a scalar quantity representing potential energy per unit charge.
Measured using a voltmeter connected in parallel across a circuit component.
Measuring cell and battery terminal voltages
Determining potential drops across components in electrical circuits
Standard unit symbol is V.
Option A (Watt) is the SI unit of power, Option C (Ampere) is the SI unit of electric current, and Option D (Ohm) is the SI unit of electrical resistance.
B is correct тАФ The SI unit of electric potential is the volt, defined as joules per coulomb.
Always keep track of fundamental SI units and their corresponding physical quantities as they are frequently tested in competitive technical exams like RRB JE.
