A nichrome wire AB, 100 cm long and of uniform cross section cross section is mounted on a meter scale the points A and B coinciding with 0 cm and 100 cm marks respectively. The wire has a resistance S = 50 ohm, Ay point C along this wire, between A and B is called a variable point to which on end of and electrical element is commeted. In the following questions this arrangement will be referred to as 'wire AB'. In the circuit adjacent arrangement it is found that deflection in the galvanometer is 10 divisions. Also the voltage across the 'wire AB' is equal to the across the galvanometer. the current sensitivity of the galvanometer is about.
