Discuss Any tips ?? Remembering formula in the UK Electrical Forum area at ElectriciansForums.net
I could pm you if you like!maybe do some practice calculations, over an dover. eventually remembering formulae becomes as easy as remembering you own name and address. now who the hell am I, and where do I live?
now that would spoil the surpriseI could pm you if you like!
transposing a formula is easy if you follow this rule.
whatever you do to one side of the equation, do same to the other. e.g:
P = IR. easy. now suppose you want to find if I as you don't know it's value, but you know the value of P and R.
so.. divide each side by R, thus maintaining the equality.
so you have
P/R =I
ssimplesss.
same principle for more complex eaquations,
Well don't leave us all in suspense Jay, what's the answer?Yes the example you gave is very easy to understand
I mean like for example.....
A 5kw unit is connected to a 230 supply and draws a current of 24 Amps
Work out the effienciency of the unit ?????????
