How does the total current relate to the individual currents in a circuit of parallel resistors?
It equals the average of the branch currents
It decreases as more parallel branches are added to the circuit
It equals the sum of the currents through each branch✓Ճիշտ պատասխան
It is the sum of the reciprocal of each individual voltage drop
Բացատրություն
Every parallel branch has the same voltage across it and draws its own current, and those branch currents all return through the source, so they add. Adding branches therefore increases total current rather than decreasing it.
