In a parallel circuit, the amperage reading at any point will be:

In a parallel circuit, the total current flowing from the source splits across the various branches. Each branch has its own separate load, which means that the current flowing through each branch can vary based on the individual resistance or impedance of those loads. Therefore, the amperage reading on the main line, which reflects the total current flowing from the source, will differ from that of any individual branch line.

This principle stems from Ohm's Law and the nature of parallel circuits; while the voltage remains constant across each branch, the distribution of current depends on the value of the loads connected in those branches. Consequently, the main line's current is the sum of the currents flowing through each branch, leading to different amperage readings at various points in the circuit. This highlights the fundamental operation of parallel circuits where total current is divided among multiple paths.
