In the above questions, if the polarity of `E_(2)` is reversed, thenA. current in both ammeters will flow in same directionB. current in both ammeters will flow in opposite directionsC. current in both ammeters can be same if `R_(1) gt R_(2)`D. current in both can be same if `R_(1) lt R_(2)`

Answer» Correct Answer - B::C
If polarity of `E_(2)` is reversed, then
`I_(2) = (E_(2))/(R_(2))` and `I_(1) = (E_(1) + E_(2))/(R_(1))`
for `I_(1) = I_(2), R_(1) gt R_(2)`
