Earth Resistance-->ni ile resistance inayotolewa na Earth Electrode kwa kuruhusu current kupita kwenda chini ya ardhi, hii hasa ina maana ya ile resistance kati ya electrode na point ya zero potential.
>>Viwango vya Earth Resistance kwa maeneo tofauti tofauti
>>Large Power Station--0.5Ohm's
>>Major Power Station -- 1.0 Ohm's
>>Small Substation --2.0 Ohm's
>>Katika maeneo mwngine -- 8.0 Ohm's
