Electrical resistance and resistivity In this topic we will discuss about what is Electrical resistance and resistivity (specific resistance). On what factors Electrical resistance and resistivity depends ? And some plot of resistivity with temperature. Electrical resistance – It is the property of a conductor to resist the flow of current through it or electrical […]
Ohm’s law proof and limitations of Ohm’s law in this topic we will discuss about Ohm’s law proof and limitation of Ohm’s law , in which we will prove Ohm’s law with the help of drift velocity , and graph [V(potential) Vs I(current) ] for non-Ohmic resistance . Ohm’s law and deduction of Ohm’s law […]
Drift velocity and its relation with current – In this topic we will discuss about drift velocity and how it is related with electric current flowing through a conductor. Drift velocity and its relation with current – As we know a metal contains large numbers of free electrons . At room temperature these electrons moves […]
Electromotive force (EMF) of the cell. In this topic we will discuss about what is Electromotive force (EMF) of the cell and it is different from potential difference . As we know electric current flows through a complete closed circuit ,when there is an source of external force which can bring the ions from low […]

Capacitance of parallel plate capacitor with conducting and dielectric slab. Capacitance of a parallel plate capacitor with a conducting slab – Let A is the area of plates and d is the separation between them is d then capacitance C0= ϵ0A/d . Let Q is the charge on the plates of the capacitor. When a […]
Non-polar and polar dielectrics – In this topic we will discuss about Non-polar and polar dielectrics and dielectric polarization with electrical susceptibility. Non polar and polar dielectrics – As we know the dielectrics are insulating material which transmit electric effect without conducting electricity . Dielectrics is of two types , Non-polar Dielectrics and polar Dielectrics […]
