Final answer:

Resistors in a series circuit carry the same current, whereas in a parallel circuit, they have the same voltage across them but different currents may flow through each based on their individual resistances. High resistance in a circuit results in a low current flow, confirming that option a) is accurate.

Step-by-step explanation:

The student's question asks which option accurately describes electrical circuits. To address the confusion, we need to understand how circuits operate with resistors and their configurations.

In a series circuit, resistors are connected one after another, making a single path for the current to follow. This means that the same current flows through all the resistors in series because there's only one way for the electrons to travel, regardless of the resistance each resistor presents.

In contrast, a parallel circuit has branches, each with a resistor, and the voltage across each branch is the same. Different currents can flow through each branch in a parallel circuit because each branch operates independently of the others. The voltage supplied to each resistor is equal to the voltage of the source, and the current through each branch is determined by the resistance of the resistor in that branch.

Therefore, option a) of the original student's question is correct, as circuits with high resistance have low current flow, and the assertions regarding parallel and series circuits are accurate in the context provided in the reference information.
