Using Mesh Current Method

**Circuit Analysis** In the given circuit diagram, we are tasked with finding the currents \( I_A \), \( I_B \), \( I_C \), \( I_D \), \( I_E \), and the power for each of the sources. The circuit consists of the following components and sources: 1. **Voltage Sources:** - A 12V voltage source is connected at the top of the circuit. The positive terminal is to the right. - An 8V voltage source is found in the bottom section of the circuit. The positive terminal is at the bottom. 2. **Current Sources:** - A 2A current source is directed upwards on the left side of the circuit. - A 3A current source is directed to the left in the middle-right section of the circuit. 3. **Resistors and their values:** - From the top left, there is a 3Ω resistor followed by a 4Ω resistor. - To the right of the 12V source, there is a 1.5Ω resistor. - On the right-hand path of the circuit, a 4.5Ω resistor is positioned before the 5Ω resistor. - In the center, connecting components, there are 6Ω resistors oriented vertically and horizontally. - At the bottom section, a 7Ω resistor and a sequence of 2Ω and 3Ω resistors are present. 4. **Node Connections:** - The nodes link various paths constituted by the aforementioned components and sources. Current designations \( I_A \), \( I_B \), \( I_C \), \( I_D \), and \( I_E \) indicate the direction of current flow in different circuit sections. **Objective:** - Calculate the branch currents \( I_A \), \( I_B \), \( I_C \), \( I_D \), and \( I_E \). - Determine the power delivered or absorbed by each source. To solve this, apply Kirchhoff's laws and Ohm's law where necessary. This involves setting up and solving simultaneous equations based on the resistances and source values to find the unknown currents and powers in the circuit.
