Internal Resistance and Current Direction

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:

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.
