Verified Answer
In a series circuit with unequal resistancesa)the highest resistance ...
The lower resistance has the high voltage. That means the highest resistance has the highest voltage drop.
View all questions of this test
In series circuits, the resistor with the greatest resistance has the greatest voltage drop. Since the current is everywhere the same within a series circuit, the I value of ΔV = I • R is the same in each of the resistors of a series circuit.
Hence, the correct option is (D)

Series Circuit with Unequal Resistances
In a series circuit, the components are connected one after another, forming a single path for the current to flow. The current is the same through all the components in a series circuit. However, the voltage drop across each component depends on its resistance. In a series circuit with unequal resistances, the following statements hold true:
The highest resistance has the highest voltage drop.
The voltage drop across a resistor is directly proportional to its resistance. According to Ohm's Law (V = IR), the voltage (V) across a resistor is equal to the product of the current (I) flowing through it and the resistance (R) of the resistor. As the resistance increases, the voltage drop across the resistor also increases. Therefore, the highest resistance in a series circuit will have the highest voltage drop.
The lowest resistance has the highest current.
According to Ohm's Law, the current flowing through a resistor is inversely proportional to its resistance. As the resistance decreases, the current flowing through the resistor increases. Therefore, the lowest resistance in a series circuit will have the highest current.
Explanation of Option D
Option D states that the highest resistance has the highest voltage drop. This is correct because, in a series circuit, the voltage drop across each resistor is additive. The total voltage supplied by the power source is divided among the resistors based on their respective resistances. Since the highest resistance will have the largest share of the total voltage, it will experience the highest voltage drop.
Conclusion
In a series circuit with unequal resistances, the highest resistance will have the highest voltage drop, while the lowest resistance will have the highest current. This understanding is crucial in analyzing and designing series circuits, as it helps in determining the behavior and characteristics of the circuit components.
