guys i really appreciate the help and reading my posts, but some sayinf 2 some saying more hehe,, can you least say which are 100% right?

ive revised over 400 questions, got a b c dss coming out me ears

What happens to the resistance when you add other items in parallel?

in series it increase
in parallel it decrease

Eh? have you starting on the beer already?

Why? Do you think they are correct?

Draw a cu and a circuit.. then add an extra circuit from the cu.. is it in series or parallel?

its in parallel

its in parallel

well done

the gs38 question edd, you think that right? as does the gs38 do the construction and use of test equipment?

thanks btw

I still think it could be worded better (the question). It would be clearer if it said the overall resistance between the phase and neutral busbars. I reckon the OP would have got it straight away then. Daz

re: Exam question help

The non stat document that is applicable to the construction and use of test equipment is?
a- bs7671
b- gn3
c - gs 38
d - osg
When a number of additional circuits are connected to a distribtion board the overall resistance will?
a- Decrease
b- remain unchanged
c- be a average of circuit value
d- increase

Which one of the following devices is suitable for PFC in excess of 60kA?
a-bs 88-2
b-bs 3036
c- bs 1362
d- bs en 60898

Where no supply is availble, a test of earth electrode resistance for a installation forming part of a TT system can be carried out using?
a-Earh fault loop impedance teste
b-a continuity tester
c- An earth electrode teste
d- a low resistance ohm metre

The earth fault loop impedance of a radial circuit must be measured at?
a-the origin of the circuit
b-any convenient part of the circuit
c-the furthest part of the circuit
d-every switch on the circuit

ANY GOOD?

Also you could add 30 new ring final circuits but with nothing pluged in the resistance wont change!!!

Very good point. Daz

No still have last wrong. Read the questions fully a couple of times before answering them.

4 and 5 wrong???

re: Exam question help

Peterpan, you still have one or two wrong, you were right on your first attempt at some of them! I wish you all the luck and I pass over to others to guide you,, Im cracking a BEER open EARLY DAY ))
