The power P delivered to a load by a current of i amperes through a resistance of 19 ohms, when 110 volts are supplied at one end of the line, is given by the formula P = 110i  19i2 . Determine the maximum power that can be delivered.
maximum power in watts =

Oh, sorry I didn't realise that I needed to provide my answer. I just want to check to see if I obtain the correct answer.
My answer is:
P=110i19i^2
P'=11038i
0=11038i
i=2.8947
P"=38 therefore a max
Max Power in watts = 2.8947 
Please repost your questions along with your answers, and a math teacher will check your work.
Also there's no need to switch user names. 
Hmmm. I agree with i at 2.89 amps
Powermax=put i in the formula for power given, and you have it.
