2 Mark question (Q.3)

Electrostatic shielding is defined as a phenomenon that is seen when a Faraday cage is used to block the effects of an electric field. The effects of external fields on the internal contents are blocked using the cage.

Applications :-

(i) In thunder strom accompany by lightening it is safest to sit inside a car , rather than near a tree or open ground. The metallic body of the car becomes an electrostatic shielding from lightening .

(ii) Sensitive components of electronic devices protected or shielded from external electric disturbances by placing metal sheets around them .

(iii) In a coaxial cable the outer conductor connected to ground provides an electrical shield to the signals carried by the central conductor.

In a cavity within a conductor, the electric field is zero. Reason: Charges in a conductor reside only at its surface.

3 Mark question (Q.3)

Kirchhoff’s Rule

(i) At any junction, the sum of the currents entering the junction is equal to the sum of the currents leaving the junction.

(ii) The algebraic sum of the charges in potential around any closed loop involving resistors and cells in the loop is zero.
