2330 lv2 203 assesment help needed

[apollo1979]

Hi,

I have done my 2330 lv 2 204-206 assesments along with the 203

I passed them all except the 203

Having waiting 6 weeks for the results the part of the test i failed has gone out of my head

Looking at the notes and course material i have it doesnt include anything that will help me revise

I know that the bit i failed had not really been touched upon during the training

the section i failed is where you need to take a reading from a circuit then calculate the impedance or at least i think it was that you are given a formula to use but having not really done more then 10 min in the class room it has me stuck

Has anyone done this exam and know how to do it?

i have my re-sit this monday only booked it friday when i got my results!! need to get it passed ASAP so i can move on

Thanks for any help anyone can offer

Stressed
Rob​

Hey not completely sure if i understand what your asking but to calculate impedance you need to use the following formula -

Impedance, Z = V
I

Its similar to working out the resistance (R) but instead your doing the impedance hope this helps!

I did my re-sit this morning it all went ok i got it this time had a clear head

was

Z= sqrtR2+(Xl+Xc)2

Okay good stuff hope you get the result your hoping for.

Was meant to do my 303 resist today but its been canceled so got to wait a few weeks not fun lol..
