find charge, power, energy
The current entering the positive terminal of a device is
and the voltage across the device is
(a) Find the charge delivered to the device between and
I would presume we use the intergal
but didn't know how to use the with this
the other related question are. (b) Calculate the power absorbed and (c) Determin the energy absorbed in .
the same as you suggested
the answer for that question in book is given as
i will see if I can do (b) and (c)
the example they had in the book was pretty much the same as you suggested.
so maybe a typo in the answers.(Cool)
(b) calculate the power absorbed
their definition of power is...."the rate of expending or absorbing energy, measured in Watts (W)"
anyway this is how I did (b) assuming yours also...
however in (c) "Determine the energy absorbed in 3s" I thot the setting in would give in Joules
isn't which is the ans
