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 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 charges has the force of repulsion and dislike has 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 same.
- Charges exist at the particles of atoms like proton 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 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 carries that 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 that means they have two charges carries.
- 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 measure current
- Its measuring unit is Ampere.
- the electric field is produced by the current that control the working of electrical devices like motor, transformer.
- Current is denoted with I
- Ohm law explain the current that says voltage applied to the body has protoptioalnl value of current about body
- The device through which current passes called conductor and theorugh which current not flow called insulator
That is a detailed post about the difference between charge and current. If you have any query ask in comments. Thanks for reading.
