All the resistance are in parallel to each other.
therefore effective resistance,
1/R = 1/2r+1/2r+1/r
1/R = 4/2r
1/R = 2/r or

effective resistance R = r/2 ohm

stuffin: thank you bro
ksharan011: just mark it brainliest if u find it helpful.
stuffin: can u tell me how we put the parallel resistor formula
stuffin: in this number
stuffin: because it is in series connection
stuffin: how
