# Difference‌ ‌between‌ ‌current‌ ‌and‌ ‌ voltage‌ ‌

There is no doubt that current and voltage are confusing terms if you won’t know their basics. Today, we will explain a detailed comparison between both of them in detail. Typically, current and voltage contrast is one of the most frequently asked subjects from the current theme of physics.

If you are tiresome with your physics subject, you may know how hard it is sometimes to remember the differences. If we take an overview, then the difference between volts & amps can help you to understand the points better. Plus, know their measurements thoroughly. Before jumping straight into the key differences, let’s talk about the voltage and current definitions. So, let’s move towards straight on the track!

## Definition of Current:

Without stretching the conversation, we want you to learn the definition of current. In easy words, the current is the velocity at which an electric charge moves past a spot in a circuit. In technical speak, the current is the velocity of flow of electrical charge.

## Definition of Voltage:

The other term that sounds like a strict teacher is voltage. In easy words, it also comes by the name of electromotive power that holds a potential contrast between two points of the charge. So, it would be effortless to remember that it is an electromotive power that separates two sturdy points from each other. ### What is the relationship between both of them?

After learning the definitions as a whole, it is crucial to know about the relationship – revolving around one circuit. So, scroll down and take a look!

Current: So, here comes the current sphere that is the precise effect (voltage standing the cause) and cannot flow without voltage. You can also say that having voltage and current at the same time is crucial.

Voltage: And, on the other hand, if we talk about the cause and current. Then, the answer would be pretty clear that voltage can exist without current.

### Key Differences Between Current & Voltage

• The common difference between them is of Units! The SI unit of voltage lives as Volts by the letter V. On the other hand, the current SI unit is the letter I. Imp. Note: 1 Volt is equal to 1 Joule/coulomb. Aside, the SI unit of current is Ampere (A). And 1 Ampere is equal to 1 coulomb/second.
• The second difference is the Inter-relation Voltage that is the cause of the current. Bear in mind that current is the result of the voltages, and it can’t flow without it.
• The third contrast is also amusing! The formula to determine voltages is: V= Work done/Charge – On the other hand, I= Charge/ Time.
• The second last difference is about Field Created. The voltages generate an electrostatic field! On the other hand, the current produces a magnetic field.
• Lastly – the change in a parallel connection. If you see a parallel connection, the voltages will remain the same beyond all the segments. However, in the same connection, the current dimes, and it got spread over all components.
