Algebra and formulas

[Jackmcleod89]

Hi,
I have started my city and guilds level 2 and I am doing the principles of electrical science section at the minute I was just wondering if anyone had any tips on how to work out equations with the formulas as easy as possible?
Thanks

What are you stuck on? the question is endless specifics may elicit more help than just a general question, I'm no expert but if you give us examples someone may be able to help, ps no homework questions please

most equations are simple. can you give an example of what sort of equation you need help with?

pete, you're getting quicker in your old age. is it the incontinence?

This is 1 out of the book
A machine lifts a mass of 50kg through a distance of 15 metres in 30 seconds what will the power required be?

Oh blimey far to much for me, forgot all about that stuff many moons ago, but I'm sure there are some young studs about who ca help, sorry Jack.

Or a transformer has a 25:1 ratio. If the input voltage is 400v, the output voltage will be?

I'd just like help with the easiest ways to work these out please
Thanks

Haha no worries thanks anyway though

No mate trying to get the results of the biopsy out of my mind, if you get my drift,

that is soooo simple. even a plumber could divide 400 by 25 and get the answer of 22mm.

Hi Tel not as well as I hoped.

pm if you don't want it all over the forum. if it's what i suspect, a family member has been there.

You've got it wrong telectrix, what will the output voltage be? Maybe not so cocky next time ay?

O/P Volts will be 16, but a plumber would go for 22. post was made in jest.
