Conquer Electricity Numericals

This class will cover electricity numericals from ground zero to the higher order questions. Clear all your concepts and say goodbye to all your fears of numericals in physics. Crystal clear concept will take you far ahead than others and the actual result will be you acing the exam in a way you could never have thought. For the love of physicsBelow are some short notes on the above topics. Students can use these as revision notes. 

Electric current - The amount of charge flowing through one cross section of a conductor is called Electric current. Its SI Unit is Ampere (A). Other units are kiloampere, mega ampere, micro ampere, milli ampere, etc.

Ohm’s Law: It states that the current flowing through a metallic conductor at constant temperature is directly proportional to the potential difference applied across its ends. 

Resistance and Resistivity - The opposition to a current flow in a wire is called resistance. Its SI Unit is ohm. 

Resistivity is the resistance offered by the wire of unit length and unit area of cross-section. Its SI unit is ohm meter.
