Difference Between Voltage and Current

What is Voltage?

The required amount of energy to move the unit charge from one point to another is known as Voltage. In other words, Voltage is the potential difference force between two points in an electric field which causes current to flow in the circuit i.e. voltage is the main cause and current is the effect....

What is Current?

Current is the rate of charge flow (electrons) passing through a point in the circuit caused by the voltage. It is represented by the symbol “I”....

Difference Between Voltage and Current

Property Voltage  Current Definition   The potential difference between two points in a circuit. The flow of electric charge in a circuit. Symbol  V I Unit   Volt (V) Ampere (A) Measured using   Voltmeter Ammeter Direction   Voltage is a scalar quantity, so it has no direction. But it can have a positive or negative value. Current is a vector quantity, and it has both magnitude and direction. The direction of current is the direction in which positive charges flow. Effect on circuit elements   The Voltage causes a flow of current in a circuit. Current is what causes electrical devices to function. The amount of current flowing through a device determines how much power it consumes. Formula   V = IR I = V/R Ohm’s Law   States that the current flowing through a conductor is directly proportional to the voltage applied across it, provided the temperature and other physical conditions remain constant. States that the voltage across a conductor is directly proportional to the current flowing through it, provided the temperature and other physical conditions remain constant. Unit Charge   1  Joule / Coulomb = 1 Volt 1 Coulomb / Second = 1 Ampere Types   Alternating Voltage and Direct Voltage Alternating Current (AC) and Direct Current (DC) Series Connection   Unequal in all components Equally distributed in all components. Parallel connection  The Magnitude of voltage remains the same in all components. The Magnitude of current varies in all components....

Conclusion

In summary, voltage and current are both essential concepts in understanding how electricity works. Voltage is the potential difference between two points in a circuit, while current is the flow of electric charge. Voltage and current are related through Ohm’s Law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it, and vice versa....
