Current Electricity and Electrical InstrumentHard
Question
In the given circuit, it is observed that the current I is independent of the value of the resistance R6. Then, the resistance value must satisfy
Options
A.R1R2R3 = R4R5R6
B.
C.R1R2 = R2R3
D.R1R3 = R2R4
Solution
Current I can be independent of R6 only when R1, R2, R3, R4 and R6 from a balanced Wheatstone′s bridge.
Therefore,
or R1R2 = R2R3
Therefore,
or R1R2 = R2R3Create a free account to view solution
