The total current in a parallel circuit is equal to the:

C
Answer
Transmitters, receivers, and measurements
Type
A
source voltage divided by the value of one of the resistive elements
B
current in any one of the parallel branches
C
sum of the currents through all the parallel branches
D
source voltage divided by the sum of the resistive elements

Answer Notes

In a parallel circuit, there are multiple paths (branches) for the electric current to flow. According to Kirchhoff's Current Law, the total current entering the parallel circuit must equal the total current leaving it. Therefore, the main source current splits into the various branches, and the total circuit current is simply the sum of the individual currents flowing through each parallel branch. Distractors like "current in any one of the parallel branches" describe a property of a series circuit, where current is the same everywhere. The option "source voltage divided by the sum of the resistive elements" incorrectly applies Ohm's law to a series resistance calculation rather than a parallel one.

Two resistors are in parallel. Resistor "A" carries twice the current of resistor "B," which means that:
