MK2 Service Wide Examination (SWE) Practice Exam

In a parallel circuit, the voltage across each component remains constant and equal to the source voltage. However, the total current (amperage) in the circuit is the sum of the currents flowing through each parallel branch. When you add more components in parallel, each one can draw its own current depending on its resistance, potentially increasing the total amperage.

This behavior is a fundamental characteristic of parallel circuits, where the voltage remains steady across all branches, and the overall current increases as more paths for current flow are added. Therefore, the correct interpretation is that the amperage increases while the voltage remains unchanged.
