## How is mesh current calculated?

The steps in the Mesh Current Method are,

- Identify the meshes.
- Assign a current variable to each mesh, using a consistent direction (clockwise or counterclockwise).
- Write Kirchhoff’s Voltage Law around each mesh.
- Solve the resulting system of equations for all loop currents.

## What is mesh current analysis?

Mesh Current Analysis is a technique used to find the currents circulating around a loop or mesh with in any closed path of a circuit.

**How do you find the current through a resistor using mesh analysis?**

As there is two different voltage source for different meshes, the current through the resistor R3 is i1+i2. Now in Mesh-2, V2, R2, and R3 are connected in series. So, the same current is flowing through the three components which is i2. So, Here are the two equations, 5 = 7i1+ 5i2 and5 = i1+ 3i2.

### Why do we use mesh analysis?

Mesh analysis (or the mesh current method) is a method that is used to solve planar circuits for the currents (and indirectly the voltages) at any place in the electrical circuit. Mesh analysis is usually easier to use when the circuit is planar, compared to loop analysis.

### What is the relation between KVL and mesh analysis?

Mesh analysis employs KVL (Equation 10.1) to generate the equations that lead to the circuit currents and voltages. In mesh analysis you write equations based on voltages in the loop but solve for loop currents.

**How do you solve mesh analysis problems?**

Steps to solve mesh analysis method

- Make sure that the circuit considered for analysis has only voltage sources.
- Label the nodes with either numbers or alphabets.
- Assign the mesh currents in each loop, such that all the current directions are in a clockwise direction.

## Is KVL and mesh analysis same?

Mesh analysis applies the Kirchhoff’s Voltage Law (KVL) to determine the unknown currents in a given circuit. Mesh analysis is also called as mesh-current method or loop analysis. After finding the mesh currents using KVL, voltages anywhere in a given circuit can be determined by using Ohms law.

## What is the concept of super mesh?

A supermesh occurs when a current source is contained between two essential meshes. The circuit is first treated as if the current source is not there. This leads to one equation that incorporates two mesh currents. This will be an equation where the current source is equal to one of the mesh currents minus the other.

**How is mesh current used in current analysis?**

Mesh current Analysis provide a procedure for electric circuit analysis using mesh current as the circuit variable. The mesh analysis makes use of Kirchhoff’s Voltage Law as a basic key to analyze the circuit.

### How to calculate mesh 1 and mesh 2?

For the mesh 1 equation, I followed the current I 1 direction and subtracted current I 2 from current I 1. For the mesh 2 equation, I followed the current I 2 direction and subtracted current I 1 from current I 2.

### Which is the strangest part of the mesh current method?

The strangest part of the Mesh Current method is envisioning circulating currents in each of the loops. In fact, this method gets its name from the idea of these currents meshing together between loops like sets of spinning gears:

**When to use KVL for mesh current analysis?**

Mesh Analysis with Current Source: Mesh analysis theorem uses KVL, in the current source we don’t know the voltage of the source rather the current. There are two possible cases for current sources. Case 1 : When the current source and voltage source are in separate mesh, as shown in the figure.
