Question

A uniform wire of resistance R is cut into two equal pieces, and these pieces are joined in parallelThe resistance of the combination is
1)R 2)R/2 3)R/4 4)R/6​

Answer 1

Answer:

2) R/2

Explanation:

1/Rp=1/R1+1/R2

R1 and R2 are equal pieces

1/Rp=1/R+1/R

1/Rp=2/R

Rp=R/2

here Rp=resistance in parallel
