<p>The electric field and electric potential are related by the equation $E = -\frac{dV}{dr}$. The expression for the electric field due to an infinitely long charged wire is given by $E = \frac{\lambda}{2\pi\epsilon_0 r}$.</p> Signup and view all the answers

<p>Electrostatic shielding is the process of reducing the electric field in a region by surrounding it with a conductor. This is achieved by allowing the excess charge to distribute itself over the outer surface of the conductor, thus neutralizing the electric field inside. It is significant in practical applications to protect sensitive electronic equipment from external electric fields.</p> Signup and view all the answers

<p>The expression for the electric field due to a charged infinite plane sheet is given by $E = \frac{\sigma}{2\epsilon_0}$. This implies that the electric field is uniform and independent of the distance from the sheet.</p> Signup and view all the answers

<p>The electrostatic potential due to a point charge is given by $V = \frac{kq}{r}$. It represents the work done in bringing a unit positive charge from infinity to a point in the electric field.</p> Signup and view all the answers

<p>Capacitance is defined as the ability of a system to store electric charge. It is given by the equation $C = \frac{Q}{V}$, where $Q$ is the charge stored and $V$ is the voltage across the system.</p> Signup and view all the answers
