Assuming the bulb as the resistors, the rank the current in the main branch of the circuit from lowest to highest is B-C-A.
What are resistors?
Resistors are the electrical component of the circuit which opposes the electric current passing through it.
In the figure A, all the current will pass through the bulb. There is only one resistor through which all the current passes.
In figure B, the current passes through the three resistors. Ultimately creating resistance three times as in figure A.
In figure C, the current get divided into the three branches of the circuit. Producing the current less than A but greater than B.
Thus, the rank the current in the main branch of the circuit from lowest to highest is B-C-A.
