FOR WIRE A ,

RA = rho L/A = rho L/pie* r square -equation 1

RB = rho 2L/pie(2r)square = rho 2L/4 pie*r square

=rho L/2 pie * r square -equation 2

RA/RB = rho L/pie * r square * 2 pie *r square/rho L

RA/RB = 2

RA = 2RB , RB = RA/2

1/Rp = 1/RA + 1/RB

=1/RA +1/RB

1/Rp = 3/RA

Rp/RA = 1/3

Hence the ratio is 1:3
