Sorry for all the questions
The maximum tabulated value for a protective device is 1.85 ohms.
And the measured R1 + R2 is 1.03 ohms
What would the maximum ze 've expected to be allowed.
A) 0.35
B) 0.82
C) 21
D) 0.21
For some reason I typed in
1.03 x 0.8 on the calculator as I had the rule of thumb figure in my head and it came out a 0.82
So I want with that and that's what the answer was
Does that mean I applied the right maths
Or did I just get coincidentally lucky?
