    Intensity is defined to be the power per unit area carried by a wave. Power is the rate at which energy is transferred by the wave. In equation form, intensity I is I=PA I = P A , where P is the power through an area A. The SI unit for I is W/m2. Electric field intensity is the strength of an electric field at any point. It is equal to the electric force per unit charge experienced by a test charge placed at that point, or E=qF. From Gauss law, considering a spherical surface with charge at its center as Gaussian surface, E(A)=ϵ0q.

    Electric charge is a physical property of matter that causes it to experience a force when kept in an electromagnetic field. Positive and negative are the two types of electric charges, commonly carried by charge carriers protons and electrons. When the net charge of an object equals to zero, the object is said to be neutral.

    According to our conventions,Potential of earth is considered to be zero.When a bird perches on the live wire only,it does not get any shock,but if it on other hand touches both the live wire and neutral wire at the same time,it gets a complete shock because live wire has high potential and neutral wire has low potential due to which a potential difference is created and thus current flows giving the bird a shock.While the same case is applicable to a man standing on the ground.When a man stands on a ground(zero potential) touching the live wire(high potential),current flows through him(as human body is a good conductor of electricity) giving him a fatal shock. ••• Note that if the man too touches the live wire as the bird does(ie,not on the ground but up in the air),he won't get any shock.

    Forces between multiple charges –Superposition principle

    As per the principle of superposition, the force on any charge due to a number of other charges is the vector sum of all the forces on that charge due to other charges, taken one at a time.

    Area vector is a vector whose magnitude is equal to the area and is directed normal to the surface.

    Area as such is a scalar. So, Area vector is defined as above for use in calculations and defining some other terms like torque on a current carrying loop in a magnetic field etc.

    The electrical potential difference is defined as the amount of work done to carrying a unit charge from one point to another in an electric field. In other words, the potential difference is defined as the difference in the electric potential of the two charged bodies.

    Drift velocity is defined as the average velocity attained by the particles (electrons) of a given material due to an electric field which is proportional to current. Ohm’s law can be expressed in terms of drift velocity as follow:

    u=μE

    Where,

    u: drift velocity (m/s)

    μ: material’s electron mobility (m2/V.s)

    E: electric field (V/m)

    Continuous charge distribution : It is basically the charge distribution for 3 dimensional objects like pencil , eraser , rod, etc. In previous topics we only learn about point charges their distribution etc. By definition, the uniform charge distribution on any 3d object is termed as continuous charge distribution.
