Dealing with an engine problem

Power is work per unit time....right?
P = W/t
Instantaneous power is then the infinitesimal amount of work done in that same amount of time......
...in other words: P = dW/dt
The rate of change of work done with respect to time.

RE:
How do you find instantaneous power?

Power is work per unit of time. So take the derivative.
Or if this is electical power multiply the instantaneous current by the instantaneous voltage.

I believe putting magnetism and electricity like electro-magnets together in a way that noone knows yet, will get instantaneous power. Magnets always have power, and putting that in an engine, I could breathe better!

20W is the average power, which varies sinusoidally between 0 and it's peak value. So peak power (max instantaneous power) is 40W.

p = vi
Instant. power is same as regular power just with time included (i.e. it's a function of time). So you'll find voltage and current at a certain moment (you'll find them as functions of time and replace the time variable with the numerical value of the actual time) and multiply! Voila, that's instant. power at a certain time. Note that you may need to deal with trig functions.

Power is defined as Work over time? Instaneous is 0 time. You'll never get it.

'what the bleep do we know?'
OMFG that movie was the biggest load of crap I ever saw. I suggest everyone out there rent it and see for yourself
".....the Native Americans didn't see Columbuses' ships because they didn't believe in ships, they just saw ripples in the water"
QUOTE FROM MOVIE ppl I'm not makeing this stuff up. ppl who act like they understand this movie are just trying to make you feel stupid. Rent it and see.

i find that there is power through prayer...and i am not one of those crazy religious people, just spiritual in my own way. :) the power of positive thinking and making contact with your source (god) is amazing! i recommend watching the documentary "what the bleep do we know?" and reading the book "the power of intention" by dr. wayne dyer.
