Question
**Problem Statement:** i. If \( R_L \) is replaced by a short circuit, complete the formula below for the application of KCL at node A. Use the symbols A, B, & C for the voltages at the nodes. **KCL at A:** \[ \frac{(A - 100)}{4} + \_\_\_ = 0A \] ii. What is the Voltage at B if \( R_L \) is replaced by a short circuit? \_\_\_ V --- **Explanation:** This problem involves using Kirchhoff's Current Law (KCL) at node A in a circuit where the load resistor \( R_L \) is replaced with a short circuit. Part (i) asks for the completion of an equation that represents the sum of currents at node A being equal to zero. Part (ii) asks for the voltage at node B when the short circuit is applied.

**Transcription for Educational Website:** ### Circuit Analysis The image displays an electrical circuit diagram featuring the following components: 1. **Voltage Sources:** - A 100V independent voltage source is connected on the left side of the circuit. - A 20V independent voltage source is connected in the lower branch of the circuit. 2. **Resistors:** - Multiple resistors are present, each with a resistance of 4 ohms. - Resistors are located between the nodes of the circuit (AB, AC, and others). 3. **Dependent Voltage Source:** - A dependent voltage source labeled \(4V_x\) is situated in the circuit. The dependent source is controlled by the voltage \(V_x\), which is the voltage across one of the 4-ohm resistors in the vertical branch. 4. **Nodes:** - The circuit is divided into three primary nodes labeled A, B, and C. - Each node serves as a junction where components connect. 5. **Load Resistor (\(R_L\)):** - A load resistor, labeled \(R_L\), is present in the right side of the circuit, connected between nodes C and the bottom of the circuit. ### Diagram Explanation This circuit diagram represents a mixed circuit configuration that includes both independent and dependent voltage sources alongside resistors. The presence of a dependent voltage source implies that the circuit analysis might require additional methods such as mesh analysis or nodal analysis, taking into account the dependency factor of \(V_x\). Understanding such circuits is crucial for grasping the principles of electrical engineering, including how electrical components interact within complex networks and how dependent sources can influence circuit behavior under various conditions.
