Current Electricity

This chapter explains the free electron theory of conduction. We will come across the experimental verification of Ohm's law. It explains the effect of temperature on resistivity. It also covers the formula for a combination of resistances.

In this chapter, we will understand the concept of terminal potential difference. It highlights the application of Kirchhoff's law and the Wheatstone bridge. It also covers the description of meter-bridge and potentiometer.
