Question

In a Wheatstone’s bridge network, resistances P =2 ohm, Q= 4 ohm, R=3 ohm and S= X ohm. Find the value of unknown resistance in Ohms, if no current flows through the section AO. Emf of the cell is 2.4 V. Ignore the internal resistance of the cell. *

Answer 1

Answer:

see as in Wheatstone’s bridge P/Q = R/S

SO 2/4 = 3/x

SO x = 6 ohm or S=  6 ohm

is  the direct answer to these question
