Electronics Engineering (ELEX) Board Practice Exam

The mesh currents in a circuit are determined using loop analysis, where each mesh current represents the current flowing around a specific loop in the circuit. In this case, the values given—2A, 1A, and 0.57A—accurately correspond to the calculated mesh currents based on the circuit's parameters and the application of Kirchhoff's Voltage Law. The rationale behind choosing these values as the correct answer lies in their direct match with the computed results from the analysis, which ensures that parts of the circuit adhere to the expected electrical characteristics and relationships established during the loop analysis. Each of these values is consistent with typical outcomes one would expect from such calculations, reflecting an accurate representation of how currents behave within the defined mesh circuits. The other options present currents that either do not match the calculations or are not grounded in realistic current flow relationships established in the examination of the circuit. Using the correct values helps in validating the application of electrical engineering principles accurately, thereby supporting successful performance on the exam.
