Find Ix

**Electrical Circuit Analysis: Determining \( I_x \)** **Circuit Description:** The circuit diagram shown consists of the following elements connected in parallel: 1. A current source providing \(2I_x\), where the direction of the current is upwards. 2. A resistor with a current of 4 mA flowing downwards. 3. Another resistor with a current of 12 mA flowing upwards. 4. A resistor with a current \( I_x \) flowing downwards. 5. A current source providing \(3I_x\), where the direction of the current is downwards. The goal is to determine the value of the current \( I_x \). **Steps to Find \( I_x \):** 1. Apply Kirchhoff's Current Law (KCL) at the node (k). **Understanding the Diagram:** - The red diamond-shaped symbols represent current sources. - The blue zigzag lines represent resistors. - The current values for each component are provided as either fixed currents or as multiples of \( I_x \), which is the unknown current that needs to be calculated. The equation at node (k) would be: \[ 2I_x + 4 \, \text{mA} = 12 \, \text{mA} + I_x + 3I_x \] Analyze and solve this equation to find \( I_x \).
