Please help
You went camping overnight but forgot to take with you a heater
and need to make one using a dc battery of V0 and spare electrical
wires of different lengths and resistivity. The battery has lead
with the resistance of Rw.
Please obtain the formula for the joule heat power and plot it
as a function of RH ( in MATLAB) and in comparison to the
resistance of the connecting leads, Rw. (Note: express RH = x Rw,
where x is the effective ratio; vary x and plot Pmax vs. x).
and Find the heating power if the heater is made out of
superconducting metal. Will this heater work and why?! What is to
happen on the molecular ( i.e. electron) level ?!
