Current Electricity

This chapter explains the free electron theory of conduction. It describes the experimental verification of Ohm's law. It briefs on 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 the meter-bridge and potentiometer.
