In which of the following ways can 1 Volt be expressed?

Correct option is A

The correct answer is: (a) 1 Joule per Coulomb
Explanation:
· Voltage (Volt) is defined as the potential difference between two points that will move 1 coulomb of charge through an energy difference of 1 joule.
· Therefore,
​$$\text{ Volt} = \frac{1 \text{ Joule}}{1 \text{ Coulomb}} = 1 \,$$​​
Information Booster:
· Volt (V) is the SI unit of electric potential difference.
· It quantifies how much energy is used to move a unit charge between two points.
· Named after Alessandro Volta, an Italian physicist.
· 1 Volt = 1 J/C, i.e., energy per unit charge.
· Used in measuring voltage in batteries, circuits, and power sources.
