ELECTRON VOLT

ELECTRON VOLT:-

 V_A=Potential of plate A                                                  

V_B=Potential of plate B

U_A=Potential Energy of plate A

U_B=Potential Energy of plate A

∆V=Potential Difference between the plates=      V_B-V_A

∆U=Electric Potential Energy difference of plates=U_B-U_A

ELECTRIC POTENTIAL AT A POINT DUE TO POINT CHARGE

ELECTRIC POTENTIAL AT A POINT DUE TO POINT CHARGE:-

We can derive this potential at point due to point charge by two methods one is by using gausses law and other is by general methods

By using gausses law

consider a charge. In order to calculate electric flux by gausses law we have to draw 

a Gaussian surface consider a spherical Gaussian surface as shown in fig. Charge is enclosed in it.
