 Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between Charge & Current. The basic difference between charge and current is that charge is a physical feature of matter while current is the flow rate of charges. As the charge is a physical characteristic of matter so it bears a force when located in the electric field. There are 2 types of charges positive, negative neutral. Due movement of charges in a certain direction current is generated.

In today’s post, we will have a detailed look at both charges and electric current with the details and compare them to find their differences. So let’s get started with Difference Between Charge & Current,

#### Difference Between Charge & Current

Charge

• A charge is a physical parameter of material that allows making interaction among each other.
• It bears force only in the electrical field and there is no effect magnetic field.
• Its measuring unit is the coulomb.
• The same type of charge has the force of repulsion and dislike has an attractive force.
• Material has no charge called neutral like neutron is neutral.
• The charge has a conserved feature that means if some amount of charge is subtracted from negative then the net charge remains the same.
• Charges exist in the particles of atoms like protons and electrons.
• The charge in the rest state has an electric field about it and in motion has a magnetic field.
• The combination of electrical and magnetic fields is called electromagnetic force.
• The coulomb is derived from the physicist Charles Augustin.
• Its other unit is ampere-hour.

Current

• The flow rate of charges or electrons is known as current.
• I=V/R
• I=Q/t
• At current due to both electric and magnetic field force exerted. • It also called a combination of charges that are passing in the device.
• Chares in motion called charge carriers cause the current to flow.
• Normally charges are electrons that caused current.
• In the case of semiconductor material current flow due to holes and free electrons which means they have two charge carriers.
• In solution, current flows due to positive and negative ions.
• Ampere is flow charges in one second.
• Ammeter used to measure the current galvanometer also measures current
• Its measuring unit is Ampere.
• the electric field is produced by the current that controls the working of electrical devices like motors, and transformers.
• Current is denoted with I
• Ohm’s law explains the current that says voltage applied to the body has a proportional value of current about the body
• The device through which current passes is called the conductor and through which current does not flow is called the insulator

### Charge vs Current

Feature Charge Current
Definition it is the quantity of electricity passing through  a circuit it is the rate at which charges flow through circuits
Unit Coulomb (C) Ampere (A)
Symbol Q I
Formula Q = I x t I = Q / t
Direction It is positive or negative depending on the charge It flows from high to low potential
Flow of energy Potential difference explains the charges flow  the flow of current driven by the power sources
Flow of matter Chares can pass through inductors and insulators Current flows through conductors
Type of quantity it is a Scalar quantity it is a vector quantity
Resistance Increasing the value of resistance decreases charge flow The flow of current decreases with resistance increases
Ohm’s Law Q = I x R V = I x R
Measurement It measured with an ammeter it measured with an ammeter or a current meter
Effect on body it can be generated through static shock or  electrocution it can generate shock or electrocution
Circuit elements Charges stored in capacitors Ressitaors cause resistance in the curent flow
Examples lightning, Charging a battery, static electricity Lighting a bulb, running a motor, charging a phone
Conservation law A charge is a conserved quantity Current is not a conserved quantity
Quantity it can be transferred and accumulated it not be accumulated only transmitted
Effect on voltage Can change voltage Can cause a voltage drop
Dependence Its value depends on the current and time it depends on voltage and resistance
Density Charge density is calculated in Couloms per square meter  Amperes per square meter is the measuring unit of Current density
