An ammeter can read current upto 5 A and it has twenty divisions between the mark 0 and mark 2A on its scale
The least count of the ammeter is
(1) 0.02 A (2) 0.01 A (3) 0.2 A (4) 0.1 A
What is the direction of induced current in the loop when the current i in the straight wire is (a) increasing (b) steady-
(1) (a) clockwise (b) zero (2) (a) anticlockwise (b) clockwise (3) (a) clockwise (b) anticlockwise (4) (a) anticlockwise (b) zero
