Electronics - Parallel Circuits - Discussion


Kirchhoff's current law for parallel circuits states that the:

[A]. sum of all branch voltages equals zero
[B]. total circuit resistance is less than the smallest branch resistor
[C]. sum of currents into a junction is equal to the difference of all the branch currents
[D]. sum of the total currents flowing out of a junction equals the sum of the total currents flowing into that junction

Answer: Option D

Any one can explain?

KCL denotes that Sum of incoming current is equal to sum of outgoing current. In a parallel circuit all branch voltages are equal.

But, numerically 2 option is also right.

As if we have, 5ohm, 10ohm and 15ohm resistance in parallel.
The net R= 2.5ohm which is smaller than the smallest resistance 5ohm in the circuit.
