Internal Resistance and Current Direction – Rankers Physics

Combination of Batteries: Practice Problem & Solution

Consider the following statements and choose the correct option. Statement A: Energy is dissipated inside a battery due its internal resistance. Statement B: In a resistor, current flows from higher potential to lower potential.  
Both the statements are correct
Both the statements are incorrect
Only statement A is correct
Only statement B is correct

Solution Explained:

To solve this problem, we apply the core principles of Combination of Batteries. Understanding the underlying formula is key to arriving at the correct answer below:

Statement A is correct because the internal resistance of a cell causes Joule heating inside it. Statement B is correct because in passive elements like resistors, conventional current flows down potential gradients.

4. Assertion (A): The drift speed of electrons in metals is small (in the order of a few \(mm/s\)) and the charge of an electron is also very small (\(= 1.6 \times 10^{-19} C\)), yet we can obtain a large current in a metal. Reason (R): At room temperature, the thermal speed of electron is very high (about \(10^7\) times the drift speed).
