hai friends,

i am in a experiment,my aim is find out steady state temperature without doing experiment,
consider iam passing a current of 1A to a heater wire(5 ohms), temperature of the wire should be increasing with time as per the heat generation formula
q= i2rt, but due to convective heat transfer(open space) q=kA dT some amount of heat transfers.so,it indicates it will reach a steady state temp

my question is that how can i find it by using formulas alone without doing experiment.

please help me in this regard
 

You have said it yourself :- It all depends on the convective heat loss, so it depends on what the physical dimensions of your 5 ohm resistor are. Will it be a carbon resistor 2 mm diam X 4 mm long, or a panel 1m X 1m ?
