# 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.

In addition to these differences in voltage and current, students can also refer to the discussion below for more information on related topics. Related articles can help students learn topics such as the equation of current, electromagnetic voltage, etc. in a specific way.

### Define voltage

Voltage, also called electromotive force, is simply energy per unit charge. In other words, voltage is the electrical potential difference between two points.

### Define current

Current is simply the rate of flow of electric charge. In simple terms, current is the rate at which electric charge flows through a circuit at a given point.

### What is Electric Potential Energy?

The electrical potential energy of a charge or any system of changes is called the total work done by an external agent to bring a charge or system of charges from infinity to the current configuration without causing any acceleration.
