Parallel Circuits - Technical MCQs

Q1:

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

ANS:D - sum of the total currents flowing out of a junction equals the sum of the total currents flowing into that junction

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.
