How is current distributed in a parallel circuit?

Is equal in all branches
Is absorbed by the circuit
Is shared between branches
Stays constant across the circuit

The correct answer is: Is shared between branches

In a parallel circuit, the total current supplied by the source is divided among the various branches of the circuit. Each branch provides a separate path for the current to flow, meaning that the current entering the junction is split into multiple pathways. This results in each branch receiving a portion of the total current based on its resistance, according to Ohm's law. For example, lower resistance branches will draw more current compared to those with higher resistance. This distribution mechanism is significant because it allows for each load to operate independently of the others. If one branch is disconnected, the current continues to flow through the remaining branches without interruption. Therefore, while the total current is shared among the branches, the amount of current in each branch varies based on the specific characteristics of the load connected within that branch. This understanding is essential for analyzing how components in a parallel configuration interact and how voltage and resistance affect current distribution in such circuits.
