Current Electricity

Simply Easy Learning

Created by Mr. Pradeep Kshetrapal, Last Updated 05-Sep-2019, Language:English

Description

Electricity has a very vast domain, so much so that we cannot imagine life without electricity. Electricity exists due to certain properties of electric charge. In this video tutorial, we will be discussing in detail topics such as Charge Carriers, Thermal Velocity, Drift Velocity, Resistivity, Conductance, Thermistors, Superconductors, Kirchoff's Laws, and Voltaic Cells.

Audience

These video classes have been designed to suit the curriculum of CBSE Class 12 students. These classes will be helpful in preparing the students for their board examinations as well as other competitive exams.
