NCERT Solutions for Class 12 Physics Chapter 3 Current Electricity: Points To Remember
Below are some important points to remember for NCERT Solutions for Physics Chapter 3 to ace your exam. Students can refer to these points while revising for a quick chapter overview. These study materials will help the students adequately prepare for the exam. The important points to remember are as follows:
A conductor’s current can be measured by its flow rate of electric charge through its cross-section.
When the area of the cross-section of the conductor is held normal to the direction of the flow of current, the current density at a point in the conductor equals the current ratio to the area.
All metals conduct electricity well in solids, and electrons are responsible for this.
Drift velocity is the average velocity of electrons moving towards a conductor’s positive end when an external electric field is applied.
Mobility is the ratio between the electron’s drift velocity and the applied electric field.
A temperature coefficient of resistivity measures how much resistivity increases per unit increase in temperature when resistivity increases linearly with temperature.
