shows how gid i am ay mate:lol:

question 2 is 53.3 i think.so b.

2 is c a think mate, mind a aint gid a electrics :lol:

i reckon 2 is C,

question 1 is D

done thevenins. ive just been given the work but not gone to the lectures becasue they clash with more important ones from this year.

I really should know this , I have the amswers in the house along with 1000 other electronics equation I had to do , have u done Thevenins or the Norton theorom yet ??

exactly, this is a retake module from last year, already fcuked it up once, lol

i really should know the answers but i nmever did like electrical modules in myu mechanical engineering degree

sorry m8

also inductance sucks lol and rectifiers

nae luck m8!

fancy doing my exams for me in a fortnight and ill have a crack at your work?

hey im stuck on a couple of questions for my uni work, they are quite simple, but hey, lol

1. a coil of wire takes 10 A from a 100 V dc supply. when connected to a 50hz ac supply of 100v it only takes 5 A. calculate the inductance of the coil.

is it:
a) 17.32 mH
b) 55.3 mH
c) 31.8 mH
d) 63.65 mH

2. what ac supply voltage is required if a half - wave recifier is to be used to drive a 24v dc motor at full speed?

a) 75.4 V
b) 53.3 V
c) 24v
d) 33.94v

cheers people, any help is much appreciated.
