In a combination circuit, how does current divide at the parallel branches?

In a combination circuit, the current divides among the parallel branches based on the resistance values of each branch. According to Ohm's Law (V = IR), the voltage across each parallel branch is the same. The current flowing through each branch is inversely related to the resistance of that branch. This means that a branch with lower resistance will carry more current, while a branch with higher resistance will carry less current.

Thus, the current is distributed in such a way that it is proportional to the conductance (the reciprocal of resistance) of each branch. This principle helps ensure that while the total current entering the parallel combination equals the sum of the currents through each branch, the division of current is not equal; instead, it reflects the differences in resistance values directly.
