When two resistors are in parallel, what is it called?
Correct Answer:
A Parallel Circuit
Explanation:
When two resistors are connected across the same two points in a circuit, they form a parallel circuit. In this arrangement, the voltage across each resistor is the same, and the current from the source splits between the two paths. This is what defines a parallel configuration, and it differs from a series circuit (where the same current flows through components laid end-to-end) and from a short circuit (which bypasses components with a very low-resistance path). A mixed circuit would combine both series and parallel portions, not be purely parallel.
