if time is removed from the equation Q=VxIxt, will it still be valid to be an equation of energy?
i need that equation to estimate the heat transfer coefficient of a nichrome wire heated using direct current,but putting time to the equation makes everything complicated..

(i'd read someone's post here that use the same equation but does not put time.. too bad i can't find that post again..)

Re: q=VxIxt

VI = power

VIt = energy

Which one do you want?

Re: q=VxIxt

Did you check on the dimensions of that 'equation'?

afaik, Q = It
where does V come into it?

It could be that Q means "heat" here, rather than electric charge. That is sort of what I assumed from the context.

OH yes. Makes sense. (I have just removed my blinkers!)
