Question

Explain the principle of meter Bridge.... The wheat stone bridge

Answer 1

hello friend,

According to wheat stone bridge if the ratio of resistance

R1/R2= R3/R4

Then there is no flow of current through resistance R3

{because in this case potential difference across the ristance R3 is become zero}

METER BRIDGE

IN meter bridge we add galvanometer at the place of R3 and at the place of R1. R2,R3 we add known resistance and and we place unknown resistance

hope it helps u
