Difference Between Charge & Current

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,

Charge

A charge is a physical parameter of material that allows 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 is 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 cause current.
In the case of semiconductor material current flows 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.
The ammeter used to measure the current galvanometer also measures the current
Its measuring unit is the 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 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

Electric Charge

Electrical charge is a feature of subatomic particles of matter that helps to show electric features
It is denoted with the symbol Q
The formula of Charge is Q=Qne
Its system international unit is Coulomb
It has two types of positive and negative charges.
Electric charge is due to electrons and protons. Electrons have a negative charge and protons have a positive charge
The law of charge conversation defines that a charge is not made not created.
Electric charge defines the electric effect in a static state and the electrical effect in a moving state.
An electrometer is used for measuring charge.

Electric Current

The flow of electric charge in a specific direction is called electric current
Current is denoted with an I letter
Its formula is $I = \frac{Q}{t}$
Its system internal unit is Aampere A
There are two types of electric current constant current and time-varying current
Electric current flow due to electrons
Electric current comes with a heating effect, electric effect.
Ampere-meter used for measuring the value of electric current

Is current the same as charge?

Current is a flow of charge and is like the flow of water. The basic difference is that charge is static and current is in flow due to electrons.

What is the relationship between current and charge?

If a neutral particle loses electrons it becomes positively charged. If a neutral body gets electrons it becomes negatively charged. Current is the rate of flow of positive charge. Current is caused due to flow of electrons ions, or other particles.

What is the formula for current and charge?

If charge Q passes through a conductor having a cross-section area in time T then I=Q/t. The SI unit of charge is coulomb and measuring occurs in coulomb per second is ‘ampere’.

Can electric current be negative?

When the circuit is solved negative current provides the actual direction of current through the circuit component in reverse of the selected reference direction.

What’s the difference between voltage and current?

Voltage is the force that causes electrons and differences in potential energy between two points of the circuit.
Current is the rate of flow of electrons and is measured in amperes called amps.

What kills voltage or current?

The shock intensity defines the amount of current applied through the body and not voltage. The electric device used at home wiring and in some conditions causes a fatal current.

What kills AC or DC current?

If we compare AC with DC than find that AC is about 5 times dangerous. The human body is resistant to DC as compared to AC. So DC has less effect on life.

Which current is strong AC or DC?

DC comes with features to store and flow high voltage and AC comes with potential for carrying and distributing high power. So in the form of potential voltage DC is higher power than AC and for potential wattage, AC is higher power than DC.
