Question

Earthing resistance of G.s.s (Gird sub station)
(a) less of 5 ohm
(b) less of 1 ohm
(c) high of 5 ohm
(d) less of 1.8 ohm

Answer 1

I think (d) less of 1.8 ohm

Answer 2

1 ohm is defined as that the resistance of an object when a current of 1

ampere flows through an object having a voltage [ potential difference ]

of 1 volt in mathematical expresssion.....,

R = V/I

1ohm =1 volt / 1 ampere
