The voltage and also current space the two significant aspects of electricity.The voltage is the type of the electromagnetic pressure whose effect reasons the circulation of electrical present in the circuit. The magnitude of a voltage and current counts on each other, however these two terms are various from each various other in part ways.

You are watching: What is the difference between current and voltage


One the the significant differences between voltage and current is that the voltage is the difference in between the 2 points and also the present is the circulation of electric charges in between these 2 points the an electrical field. Part others differences between them space explained below in the compare chart.

Definition that Voltage

The voltage is the kind of the electromagnetic force. Once the size of the voltage is high, big current circulation through the circuit and when their magnitude is short less current flow v it. The voltage is stood for by the prize V, and also their SI unit is volt.

Voltage is mainly classified into two type, i.e., the alternate voltage and direct voltage. The alternating voltage changes its polarity, and the direct voltage does not change its polarity. The straight voltage is created by the potential difference between the terminal of the electrochemical cell, and the alternate voltage is caused by the alternator.

Sometimes in a transmission line, the voltage at the sending end is much less than the voltage at the receiving end. The voltage is dissipated in the type of the heat and also hence this loss of voltage is called voltage drop. The voltage fall occurs because of heavy load. As soon as the heavy load is connected throughout the line, it draws heavy existing due come which voltage ns occurs.

When the receiving end voltage is greater than the sending finish voltage, then the voltage increase occurs in the line. The climb in voltage is called Ferranti effect, and also it mainly occurs due to the fact that of the charging current of the infection line.


Definition that Current

The existing is the impact of the voltage. As soon as the potential difference is applied throughout the conducting material, the electrical charge carrier starts moving from one atom come another. The present is stood for by the symbol I and their SI unit is ampere. The one ampere of existing represents the 6.24×1018 fee carrier. The bulk of the fee carriers are an unfavorable charge carrier, and the direction of circulation of existing is indigenous the an unfavorable point to relatively positive point.

The electrical existing is mainly separated into two types, i.e., the alternate current and also direct current. In straight current, the electrons flow only in direction and also in alternate current the direction of electron reversed in every millisecond.


Key Differences between Voltage and Current

The voltage is the difference of the electrical charges between the two point of an electric field, whereas the existing is the circulation of the electric charges between the allude of an electrical field.The SI (International unit of the standard) unit that the voltage is volts, and also the SI unit the the existing is amperes.The voltage is stood for by the prize V whereas the current is stood for by the symbol I.The voltage is characterized as the ratio of the job-related done come the charge, whereas the current is the proportion of the fee to the timeThe voltage generates the magnetic field about it vice versa, the current generates the electrostatic field roughly it.The polarity that the alternative voltage remain changes and also due to this alternating voltage, the alternative current induces. But the polarity that the direct voltage stays constant, and also their impact induces a direct current.The voltage is the difference in between the point in an electrical field, vice versa, the existing is led to by the circulation of the electron in the electric field.The voltage is measured by an instrument called a voltmeter whereas the current is measure by the ammeter.The one volt is same to the 1 joule/coulomb whereas the one ampere is equal to the one column/second.In a collection circuit, the size of voltage remains different in all the component of the circuit conversely, the size of current remains same.In the parallel circuit, the voltage at all the branches the the circuit remains same conversely, the present is unequally distributed in the circuit component.The voltage drop greatly occurs because of the impedance that the circuit conversely, the current drop occurs as result of the passive aspect (like a resistor) of the circuit.The impedance is the obstruction cause by an electric circuit come the circulation of an electrical present when the potential difference is applied across them.The voltage is the reason of the present whereas the present is the result of the voltage.

Conclusion

According come ohm’s law, the voltage is directly proportional come the current. The quantitative voltage is generated when the flux is reduced by the conductor which is placed between the rotating magnetic field. This voltage cause the existing in the circuit. Thus, we can say the the voltage deserve to exist there is no current, but current can not exist without voltage. In various other words, the present is the effect of the voltage, and the voltage is the cause of the current.
