If the polarity of `E_(2)` is reversed, then

A

current in both ammeters will flow in same direction

B

current in both ammeters will flow in opposite directions

C

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)`

Text Solution

Verified by Experts

The correct Answer is:
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)`
