📘 𝐖𝐡𝐞𝐚𝐭𝐬𝐭𝐨𝐧𝐞 𝐁𝐫𝐢𝐝𝐠𝐞: 𝐀𝐬𝐬𝐞𝐫𝐭𝐢𝐨𝐧 & 𝐑𝐞𝐚𝐬𝐨𝐧𝐢𝐧𝐠 𝐂𝐡𝐚𝐥𝐥𝐞𝐧𝐠𝐞

𝐃𝐢𝐫𝐞𝐜𝐭𝐢𝐨𝐧𝐬:

(𝐀) Both 𝐀 and 𝐑 are true, and 𝐑 is the correct explanation of 𝐀.
(𝐁) Both 𝐀 and 𝐑 are true, but 𝐑 is 𝐍𝐎𝐓 the correct explanation of 𝐀.
(𝐂) 𝐀 is true, but 𝐑 is false.
(𝐃) 𝐀 is false, but 𝐑 is true.


𝐀𝐬𝐬𝐞𝐫𝐭𝐢𝐨𝐧 (𝐀): In an unbalanced Wheatstone Bridge, the central branch resistor cannot be ignored during equivalent resistance calculations.

𝐑𝐞𝐚𝐬𝐨𝐧 (𝐑): Kirchhoff’s Voltage Law (𝐊𝐕𝐋) states that the sum of potential drops in any closed loop must be zero.

UNIT 12: CURRENT ELECTRICITY 🧠 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?

(𝖠) F = ε₀AV²/d² ; because the charges react to the total field (V/d) between the plates.

(𝖡) F = ε₀AV²/2d² ; because one plate reacts only to the field (V/2d) produced by the other plate.

(𝖢) F = ε₀AV²/2d² ; because the energy stored in the capacitor is equally shared by both plates.

(𝖣) F = ε₀AV/d ; because the force is independent of the distance between the plates.
