Question

Use Mesh Current Method

This image presents a circuit diagram with the following components and resistances:

- On the left, there is a 10V DC voltage source.
- Several resistors are connected as follows:
  - 750Ω, 680Ω, 470Ω, 150Ω, and 330Ω around the voltage source, forming a loop.
  - 910Ω, 1.3kΩ, 330Ω, and 430Ω form a branch at the top.
  - 510Ω, 220Ω, and 430Ω form another branch on the right.
  - 360Ω, 110Ω, and 240Ω run through the center in another path.

**Analysis:**

1. **Check for Planarity:**
   - A planar circuit can be drawn on a plane without any wires crossing each other. To determine if this circuit is planar, examine if any of the connections or branches can be redrawn without overlapping.

2. **Determine the Number of Meshes:**
   - A mesh is a loop that doesn’t contain any other loops inside it. To find the number of meshes, consider the loops that can be formed by the components:
     - Count the number of unique, independent pathways that can be drawn.

By analyzing the given resistances and configurations, one can evaluate if the circuit is planar and identify the number of independent meshes present within the circuit.
