In the shown arrangement of the experiment of the meter bridge if AC corresponding to null defle-ction of galvanometer is x, what would be its value if the radius of the wire AB is doubled? |

Answer» Solution :For null deflection of GALVANOMETER in a METREBRIDGE experiment, `(R_(1))/(R_(2))=(R_(AC))/(R_(CB))=(x)/((100-x))` Since `R_(1)//R_(2)` remains CONSTANT, `x//(100-x)` also remains constant. The VALUE of x remains as such. `therefore "Length of AC = x"` |
