If the current at one corner of the 12V series circuit is 1.0 A, what is the current at corner number three (all three resistors are the same).

To determine the current at corner number three in a series circuit with three equally sized resistors, we need to understand how current behaves in a series circuit.

In a series circuit, the current remains the same at all points. This means that the current at one corner will be equal to the current at any other corner.

Given that the current at corner number one is 1.0 A, we can conclude that the current at corner number three is also 1.0 A.

Therefore, the current at corner number three in this circuit is 1.0 A.
