2 only please **Educational Circuit Analysis Problems:**Welcome to the circuit analysis section. Below are a few circuit problems to help you practice your electrical engineering skills.1. **Node Voltage Method Problem:** - **Task:** Using the node voltage method, find the voltage at the essential nodes in the circuit below. - **Circuit Description:** - A circuit with a 25V voltage source is connected to resistors with values 3Ω, 2.5Ω, 10Ω, and 5Ω, and a current source of 3A. The resistors and sources form a network with essential nodes to analyze.2. **Mesh Current Method Problem:** - **Task:** Label the mesh currents in the circuit below, and write the equations for the mesh currents. Do not solve the equations, just write them. - **Circuit Description:** - The circuit includes a 20V voltage source, a 30V voltage source, and a 2.5V voltage source, arranged with resistors of 4Ω, 7Ω, 6Ω, 3Ω, and 9Ω. The circuit forms multiple loops (meshes) for analysis.3. **Norton Equivalent Circuit Problem:** - **Task:** Find the Norton equivalent circuit for terminals a + b in the circuit below by using source transformation. - **Circuit Description:** - It includes a 5A current source in parallel with a 5Ω resistor, and a series connection of a 3Ω resistor and a 10V voltage source. The goal is to simplify this circuit to its Norton equivalent between terminals a and b.**Diagrams Explained:**- Each problem includes a detailed circuit diagram with components clearly labeled, including voltage and current sources as well as resistors.- Nodes, meshes, and terminals are indicated where necessary for problem-solving. These problems provide a practical learning experience in applying the node voltage method, the mesh current method, and source transformations to find equivalent circuits.
