Electrostatics and Electric Current – Physics Unit 4 – Class 12 – Maharashtra Board

Electrostatics and Electric Current – Unit IV consists of two chapters:

1. Chapter 8 – Electrostatics
2. Chapter 9 – Current Electricity

After studying the content, students would be able to

• Use Gaus’s law to obtain the electric field for a charge distribution.
• Relate potential energy to work done to establish a charge distribution.
• Determine the electrostatic potential for a given charge distribution.
• Distingusih between conductors and insulators.
• Visualize polarization of dielectrics.
• Categorize dielectrics based on molecular properties.
• Know the effect of dielectric material used between the plates of a capacitor on its capacitance.
• Apply Kirchhoff’s laws to determine the current in different branches of a circuit.
• Find the value of an unknown resistance by using a meter bridge.
• Find the emf and internal resistance of a cell using potentiometer.
• Convert galvanometer into voltmeter and ammeter by using a suitable resistor.
