UNIT 12: CURRENT ELECTRICITY ๐ง Tricky Question: Wheatstone Bridge Concepts-NCERT 3.13 WHEATSTONE BRIDGE
Assertion (A): An electrical circuit consisting of four resistors arranged in a diamond shape is considered a Wheatstone bridge only if the galvanometer shows zero deflection.
Reason (R): The balanced state is a specific condition of the bridge where the potential difference across the galvanometer terminals is zero.
Select the correct option:
(1) Both (A) and (R) are True, and (R) is the correct explanation of (A).
(2) Both (A) and (R) are True, but (R) is NOT the correct explanation of (A).
(3) (A) is True, but (R) is False.
(4) (A) is False, but (R) is True.

UNIT 11: ELECTROSTATICS
Consider a parallel plate capacitor (Area A, separation d) connected to a battery of potential V. Which of the following correctly describes the magnitude and physical origin of the attractive force (F) between the plates?
(๐ ) F = ฮตโAVยฒ/dยฒ ; because the charges react to the total field (V/d) between the plates.
(๐ก) F = ฮตโAVยฒ/2dยฒ ; because one plate reacts only to the field (V/2d) produced by the other plate.
(๐ข) F = ฮตโAVยฒ/2dยฒ ; because the energy stored in the capacitor is equally shared by both plates.
(๐ฃ) F = ฮตโAV/d ; because the force is independent of the distance between the plates.
