As shown in figure "A" of the illustration, with the switch closed what statement is true if 'R1' and 'R2' have unequal resistance values? Illustration EL-0019
AI Explanation
The correct answer is D) The current flow through 'R1' will differ from the current flow through 'R2'.
This is because when 'R1' and 'R2' have unequal resistance values and the switch is closed, the current flowing through each resistor will be different. According to Ohm's law, the current is inversely proportional to the resistance, so the resistor with the lower resistance will have a higher current flow compared to the resistor with the higher resistance.
The other answer choices are incorrect because: A) The energy dissipated in each resistor will be different due to the unequal current flows, B) The voltage drops across the resistors will be different due to the unequal current flows and resistance values, and C) The current flows through the resistors will not be equal.
