A nichrome wire AB, long and of uniform cross section is mounted on a meter scale the points A and B coinciding with and marks respectively. The wire has a resistance . Any point C along this wire, between and is called a variable point to which on end of and electrical element is connected. In the following questions this arrangement will be referred to as ‘wire AB’ .

Question 1 (1 of 1 Based on Passage)

Appeared in Year: 2016



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 that across the galvanometer. Therefore, the current sensitivity of the galvanometer is about –
