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.
