A .25 kg length of aluminum wire is warmed 10 deg.Celsius by an electric current.How much generated by current

Answer 1

I like these compbo question ;-)

I think some information is missing but we can always solve it algebraically.
We know that power (P) loss in a conductor is
P=I^2R
I - current
R - resistance
also a certain amount of energy (W) is required to heat that mass of wire
P=W/t
W -energy required to heat
t - time it tool to change by 10 C.

W=Cp dT
Cp - Specific heat capacity
dT change in temperature

So P=Cp m dT/t
Cp=0.897 Joules / (gm K)
dt= 10C (and since it is the difference also = 10 K)
m = 250 gm
t- is not given
however
P=Cp m dT/t
is the solution
