FAQs on 3 Days Timetable: Electrostatic Potential and Capacitance (2025) - Physics for JEE Main & Advanced

1. What is the definition of capacitance and how is it calculated?
Ans.Capacitance is defined as the ability of a system to store electric charge per unit voltage. It is calculated using the formula \( C = \frac{Q}{V} \), where \( C \) is the capacitance in farads (F), \( Q \) is the charge stored in coulombs (C), and \( V \) is the potential difference in volts (V) across the capacitor.
2. How does the electric potential due to a dipole differ from that of a single charge?
Ans.The electric potential due to a dipole decreases with distance more rapidly than that of a single point charge. For a dipole, the potential \( V \) at a point in space is given by the formula \( V = \frac{1}{4\pi\epsilon_0} \frac{\mathbf{p} \cdot \hat{r}}{r^2} \), where \( \mathbf{p} \) is the dipole moment, \( \hat{r} \) is the unit vector in the direction from the dipole to the point, and \( r \) is the distance from the dipole. This shows that the potential decreases as \( \frac{1}{r^2} \) instead of \( \frac{1}{r} \).
3. What are equipotential surfaces and why are they important in electrostatics?
Ans.Equipotential surfaces are regions in space where the electric potential is constant. They are important because no work is done when moving a charge along an equipotential surface, which implies that the electric field is always perpendicular to these surfaces. This concept helps in visualizing electric fields and understanding the behavior of charges in electrostatic situations.
4. What are the characteristics of conductors in electrostatic equilibrium?
Ans.In electrostatic equilibrium, conductors have specific characteristics: the electric field inside a conductor is zero, excess charge resides on the surface, and the surface is an equipotential surface. Additionally, if placed in an external electric field, the charges within the conductor rearrange themselves to cancel the field inside, ensuring that the conductor remains electrically neutral inside.
5. How can capacitors be combined in series and parallel, and what are the formulas for their equivalent capacitance?
Ans.Capacitors in series and parallel combine differently. For capacitors in series, the equivalent capacitance \( C_{eq} \) is given by \( \frac{1}{C_{eq}} = \frac{1}{C_1} + \frac{1}{C_2} + \ldots \). For capacitors in parallel, the equivalent capacitance is the sum of the individual capacitances: \( C_{eq} = C_1 + C_2 + \ldots \). This understanding is crucial for solving complex circuits involving capacitors.
