Earthing resistance

[Luke Abley]

Hello wondered if anyone can help. I have an exam in a couple of weeks and need to know this. Googled it but can really find an answer. The question is. What is the maximum allowable value of earthing resistance of a conductor by your local standards. Thanks in advance

The question doesn't really make sense. The maximum impedance for various scenarios varies depending on several factors.

What exam is it?

It's an exam for a visa for Australia. I can't get my head round it. If it was ze then it would say that. Why can't they just word it better

yes. it's a silly question. the resistance of a conductor is proportional to it's length, and inversly proportional to it's csa.

I might give them a ring cos it don't make sense.
