One example of a water system is a garden hose that waters a garden. Another is the cooling system of an automobile. Which of these exhibits behavior more analogous to that of an electric circuit? Why?
To identify: Whether the garden hose or cooling system of automobile is more analogous to electric circuit.
Answer to Problem 25A
The cooling system of automobile is more analogous to electric circuit.
Explanation of Solution
Introduction:
The temperature of the cooling system is like the voltage, heat is like current and thermal resistance is like the electric resistance of the electric circuit.
The pressure of the water system is like the voltage, amount of water is like current and hydro resistance is like the electric resistance of the electric circuit.
The variables of cooling system of the automobile and water system of garden hose are same as the electric circuit but the cooling system of the automobile is the closed circuit. So, the cooling system of the automobile is more analogous to electric circuit.
Conclusion:
The cooling system of the automobile is more analogous to electric circuit because cooling system and electric circuit both follow the closed path.
