Answer

Wheat stone bridge follows.P/Q=R/S, condition. b) P=2, Q=3 ,R= 4,S=62/3=4/62/3= 2/3...

Answer

Wheat stone bridge follows

P/Q = R/S

So 2/3 = 4/6

Answer

B

Answer

Wheat stone bridge follows

P/Q = R/S

So 2/3 = 4/6

Answer

Explanation:

Wheatstone Bridge:
A Wheatstone bridge is a circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit.

Balanced Wheatstone Bridge:
In a balanced Wheatstone bridge, the ratio of resistances in the two legs is equal. This means that the product of the resistances in one leg is equal to the product of the resistances in the other leg.

Given Resistances:
The resistance values given in the options are:
a) 3, 4, 5, 6
b) 2, 3, 4, 6
c) 1, 2, 3, 4
d) 3, 4, 6, 5

Calculating the Ratios:
For option 'B' (2, 3, 4, 6):
Product of resistances in one leg = 2 * 3 = 6
Product of resistances in the other leg = 4 * 6 = 24
Since the two products are not equal, option 'B' is not balanced.

For option 'A' (3, 4, 5, 6):
Product of resistances in one leg = 3 * 4 = 12
Product of resistances in the other leg = 5 * 6 = 30
Since the two products are not equal, option 'A' is not balanced.

For option 'C' (1, 2, 3, 4):
Product of resistances in one leg = 1 * 2 = 2
Product of resistances in the other leg = 3 * 4 = 12
Since the two products are not equal, option 'C' is not balanced.

For option 'D' (3, 4, 6, 5):
Product of resistances in one leg = 3 * 4 = 12
Product of resistances in the other leg = 6 * 5 = 30
Since the two products are not equal, option 'D' is not balanced.

Therefore, the balanced Wheatstone bridge is in option 'B' (2, 3, 4, 6).
