Answer
Based on the options provided, the best fit for what
represents in the given formula is (B) Total earth fault loop impedance. This is because the total earth fault loop impedance would include the external earth fault loop impedance (represented by
) and the combined resistance of the earth path (represented by
).
Explanation
## Step1: The given formula is \( Z_{s}=Z_{e}+\left(R_{1}+R_{2}\right) \). In this formula,
is the subject of the formula, which means it is what the formula is solving for or representing. ## Step2: The formula is adding
(which could represent an external impedance) and the sum of
and
(which could represent resistances) to get
. ## Step3: Given the nature of the formula, it is clear that
is representing a total impedance that includes an external impedance and the sum of two resistances.
