Answer 1

Answer #1

When the resistances are connected in parallel

the net resistance will be

Rnet = R/4

hence ,for the current

new current = 4 * old current

new current = 4I

=============================================

when R2 is replaced by a wire

all the current will pass through the wire

the current in R1 will be 0 A
