A) 20\[{{i}_{2}}>{{i}_{1}}>{{i}_{3}}\]
B) 2\[{{i}_{1}}>{{i}_{2}}>{{i}_{3}}\]
C) 0.2\[{{i}_{1}}>{{i}_{3}}>{{i}_{2}}\]
D) 2\[\sqrt{30}\]
Correct Answer: B
Solution :
Let \[{{\phi }_{0}}\]be the current flowing through ammeter and i the total current. So, a current \[\frac{T}{4}\] will flow through shunt resistance. Potential difference across ammeter and shunt resistance is same, ie, \[\frac{T}{8}\] or \[\frac{T}{12}\] ?...(i) Given, \[\frac{T}{2}\] Hence, \[\lambda \]You need to login to perform this action.
