Why does the different in temperature between 2 body determine the rate of heat transfer?
Why does the temperature gradient decrease as it reaches thermal equilibrium/fixed point of a substance?
Apart from using the equation Rate of heat transfer = kA (Difference in temperature) / d

Unlimited power source?
Usually the A.C. supply at the primary coil is from an A.C. generator at power station. hence according to conservation of energy (power).. kinetic energy is converted to electrical energy.
With a load ( e.g. 1 ohm) at the secondary coil and hence drawing power of...
I am confused about this. Say the rating is 2400 W and now the primary delivers 14.4kW because secondary coil is now loaded and requires 14.4kW.
Where does this "extra" power of 14.4 - 2.4 kW come from?
