Electrostatic refers to the process of matter becomes Electric Charge
Normally all matter are neutral or have net Charge equal to zero . When an object loses electron it becomes Positive Charge . When an object gains an electron it becomes Negative Charge
- Matter + e --> [-]
- Matter - e --> [+]
All Electric Charges pocess a Quantity of Electric Charge called Electric Charge denoted as Q measured in Couloum (C) .
- Positive Charge, +Q
- Negative Charge, -Q
Electric Field is defined as Electric Field Lines radiate outward for Positive Charge or inward for Negative Charge. Electric Field is denoted as E measured in N/C .
- Negative Charge , E . ---> Negative Charge <--- .
- Positive Charge , E . <--- Positive Charge --->
Magnetic Field is defined as Elliptical Magnetic Field Lines rotates in clockwise direction for Negative Charge and Counter-Clockwise for Positive Charge
- Negative Charge , B .
- Positive Charge , B .
Interaction between Charges
Charges interact with each other according to Coulomb's Law and creating Electric Force between Charges as follow
- Like Charges repulse . Unlike Charges attract , Negative Charge attract Positive Charge .
- When different charges interact with each other example Nagative Charge attracts Positive Chrages creates Kinetic Energy in Electricity.
- When there is a difference in Charge's Quantities that creates Potential Difference in Electricity
- mQ - nQ = (m-n) Q
If there is a Electromotive Force that sets stationary charge to move in straight motion to cause a flow of charges called Current then the Electric Field can be calculated by Ampere's Law as follow
If there is a ElectroMagnetomotive Force that can change the direction of the moving charge perpendicular to the initial direction of moving charge such that Positive charge will moved up perpendicular to the initial direction and Negative Charge will move down perpendicular to the initial direction then Magnetic Field can be calculated by Lorenzt's Law
ElectroMagnetic Force is the total force acting on the moving charge equals to the sum of the Electromotive Force calculated by Ampere's Law plus the Magnetomotive Force calculated by Lorentz's Law.
Matter and Electricity
- All matter that allows current to flow with ease are called Conductor. For example all Metals like Zinc (Zn), Copper (Cu) are used to make Conductor
- All matter that does not allow current to flow in it are called Non Conductor . For example Rubber
- All matter that allows current to flow somewhere between conductor and non conductor are called Semi Conductor . For example Silicon (Si), Gemanium (Ge)
