Question

: Fig shows a cell and an ammeter of
negligible resistance. All the resistors are similar. The ammeter
shows a current of 1.2 A when switch K is open. What will be the
ammeter reading when the switch is closed ?
​

Answer 1

Answer:

in the diagram shown below, the cell and the ammeter both have negligible resistance . the resistors are identical with the switch k open ,the ammeter reads 0.6 A . what will be the ammeter reading when the switch is closed
