In electricity, current, and voltage there are many crucial elements to understand. Though they are linked and aid in the operation of electricity. A voltage may exist without a current, but current can never exist without a voltage difference. Ohm’s law, which binds voltage and current together, is the foundation of electricity.

V (in Volts) = J (Energy in Joules) /C (Charge in Coulombs) = W (Work done in joules) /A (Current in Ampere)
Main Differences Between Current and Voltage
- The rate of flow of electrical charges between the points of an electrical field is known as current. The voltage is the difference in electrical charges in between 2 points present in a uniform electric field.
- Amperes are the SI unit of current. Volt is the unit of voltage.
- The current is symbolized by “I”, whereas the voltage is signified by “V”.
- The charge to time ratio is recognized as the current. Whereas The voltage is the work done per unit charge.
- The electrostatic field that surrounds the electric current is created by it. The magnetic field surrounding it is created by the electric voltage.
Conclusion
The electrical voltage is directly proportional to the electric current, according to Ohm’s law. When the flux is reduced by the conductor positioned between the spinning magnetic field, the quantitative voltage is created. The current is induced by this voltage. As a result, we may argue that electric current can exist without voltage, while voltage cannot exist without current. The current is the consequence of the voltage, whereas the voltage is the source of the current. The Current and voltage are electrical antiquates that are linked to one another. For and electronic and electrical engineering, as well as all other fields using electricity, understanding the principles of voltage and current, is critical.
