Let us give the equation number 1 to this and the equation for flow of electricity that is ohm's law is I is equal to V upon R or we can write it as I is equal to delta V upon R equation number 2. By comparing equations 1 and 2 we get the analogy between flow of heat and electricity. The analogy can be written as the quantity which is there electrical quantity and heat quantity. Now on left hand side we are finding that in case of heat it is the heat flow rate which is equivalent to current in case of electrical energy. Current we express in ampere heat flow rate is expressed in watts. The second analogy in the numerator of two equations in case of electricity it is a voltage or potential difference which causes flow of electricity whereas in case of heat it is the temperature difference or thermal potential which we can express in terms of degree Celsius or degree Kelvin. Potential difference we express in terms of fold and in the denominator we have the quantity under electrical we have electrical resistance which is expressed in ohm's and thermal resistance which is a unit of degree Kelvin per watt. So this method we can use to solve the heat transfer problem using the by developing the electrical circuit. The references which you can use is heat transfer by P.K. Nag and heat and mass transfer by R.K. Rajput. Thank you.
