What is Difference Between Voltage And Current
The difference between voltage and current is explained here in detail. One of the most frequently asked questions on the topic of electricity and physics is the difference between current and voltage.
The differences between volts and amperes presented here can help students better understand basic concepts and their comparisons.
Before determining the difference between voltage and current, it is important to understand the details of voltage and current. Please visit the links below for detailed voltage and current with other information.
Difference Between Voltage And Current
| Sl. No. | Differentiating Property | Voltage | Current |
|---|---|---|---|
| 1 | Definition | Voltage, also called electromotive force is simply the energy per unit charge. In other words, voltage is the difference in electric potential between two points. | Current is just the rate of flow of electric charge. In simple words, the current is the rate at which electric charge flows in a circuit at a particular point. |
| 2 | Unit | The SI unit of voltage is Volts (V).
Note: 1 Volt= 1 Joule/coulomb. |
The SI unit of current is Ampere (A).
Note: 1 Ampere = 1 coulomb/second. |
| 3 | Denotation | Voltage is denoted by “V”. | Current is denoted by “I”. |
| 4 | Measuring Instrument | Voltage can be measured by using a Voltmeter. | Current can be measured by using an Ammeter. |
| 5 | Inter-relation | Voltage is the cause of the current. | Current is the effect of the voltage i.e. current cannot flow without voltage. |
| 6 | Formula | One of the formulae to calculate voltage is:V= Work done/Charge | One of the formulae to calculate current is:I= Charge/ Time |
| 7 | Loss | The loss of voltage occurs due to impedance. | The loss of current occurs due to the passive elements. |
| 8 | Field Created | Voltage creates an electrostatic field. | Current creates a magnetic field. |
| 9 | Change in a Series Connection | In a series connection, voltage changes i.e. it gets distributed over all the components. | In a series connection, the current remains the same through all the components. |
| 10 | Change in a Parallel Connection | In a parallel connection, the voltage remains the same across all the components. | In a parallel connection, current changes i.e. gets distributed over all components. |
This was the main difference between voltage and current. This difference in current and voltage can help students to understand this in detail and be able to answer any relevant questions easily in exams.
