Question

In a series circuit of two resistors, the resistors have the same __________; in a parallel circuit of two resistors, the resistors have the same __________.

A. Current through them, current through them
B. Current through them, voltage across them
C.Voltage across them, voltage across them
D. Voltage across them, current through them

Answer 1

In a series circuit, resistors have the same current through them; in a parallel circuit, resistors have the same voltage across them, making option B the correct answer.

Step-by-step explanation:

In a series circuit of two resistors, the resistors have the same current through them; in a parallel circuit of two resistors, the resistors have the same voltage across them. Therefore, the correct answer would be B. Current through them, voltage across them. This is because in a series circuit, the resistors are connected end-to-end in such a way that there is only one path for current to flow, meaning all resistors have the same current flowing through them. Conversely, in a parallel circuit, each resistor is connected directly across the power supply, so they all have the same voltage across them but can have different currents flowing through, dependent on their individual resistances.
