**byjus.com**Nodal analysis is a process through which circuits can be analyzed. Here, you need to use the node voltages as the circuit variable. Another name for **node analysis** is **node voltage** method.

The following are some Nodal Analysis features:

- Based on Kirchhoff’s Current Law, nodal analysis is built (KCL).
- There will be “n-1” simultaneous equations to solve with “n” nodes.
- You can find The nodes’ voltages by solving ‘n-1’ equations.
- The number of possible nodal equations equals the number of non reference nodes.

**Learn how to use reference node**

When employing Nodal analysis to solve any electrical network or circuit, the following are the steps.

Choose one of the central nodes to serve as the reference node in **nodal system steps**.

**Step 1**. That reference node will be regarded as the Ground.**Step 2:**Label all primary node voltages concerning Ground, excluding the reference node.**Step 3:**Leaving the reference node, write nodal equations at each central node. KCL is used first, followed by Ohm’s law, to produce the nodal equation.**Step 4:**To get the node voltages, solve the nodal equations you received in Step 3. We can now identify the stream flowing.

**iceeet.com****Non Reference Node:** A non reference node has a fixed Node Voltage. e.g., The Non Reference Nodes, in this case, are Node 1 and Node 2.

A reference node serves as a point of reference for all other nodes in the network. The Datum Node is another name for it. **Electrical Sources**

Independent and dependent electrical sources are the two categories under which they fall.

A circuit is connected to a separate electrical source that outputs a predetermined amount of current or voltage. The only sources here are power supply and batteries. In this case, the power supply provides a stable fixed value while the batteries eventually provide a stable, limited value without recharging. You must know the **node voltage analysis** as well.

**Linear Dependent Sources**

The four categories of linearly dependent sources are as follows.

- Voltage-controlled voltage source
- Current-controlled current source
- Current-controlled voltage source
- Voltage-controlled current source
- You will be able to observe
**a number of nodal equations.**

The o/p of a voltage-controlled voltage source is “V,” the voltage gain is “AV,” and the parameter being detected is “VCD.” This linear dependent source is related by the equation shown below.

V = Av VCD

In a voltage source controlled by current, the o/p is V, the resistance is RM, and the measured parameter is IC. The equation below can be combined through a **nodal analysis with voltage source** with current control.

V = RvM IC

The current gain and the parameter detected are the o/p and Ai, respectively, in the current-controlled current source. A current-controlled current source can be used to connect the following equation.

I = AI Ic

The o/p in a voltage-controlled current source is “I,” the conductance is “GM,” and the parameter being measured is “VCD.”

**Differences between nodal analysis and mesh**

The following are some ways that mesh and nodal analysis differ from one another.

In contrast to mesh analysis, which uses current values in a specific branch of a circuit, nodal analysis of electricity systems allows for observing voltages at a given unit.

Mesh analysis is one technique used in the electrical network to solve planar circuits, specifically for the current flow at any branch. Without putting any wires in contact with one another, these circuits can be sketched on a flat surface. Any course employs a more all-encompassing technique called loop analysis.

The KCL (Kirchhoff’s Current Law) application is necessary for nodal analysis. There will be “n-1” instantaneous equations to solve if the circuit has n nodes.

**Fundamental Procedures in Nodal Analysis**

To each of the non-reference nodes, apply KCL.

To translate branch currents into node voltages, use Ohm’s law.

Node consistently expects that the current in a resistor moves from a more significant potential to a lower potential. The following is how current is expressed.

**Nodal analysis with current source**

**nodal analysis examples**include a discussion on

**using nodal analysis**. Also, it uses

**an electrical circuit**.

In the below-mentioned circuit, we can see three nodes. One is a reference node, and the other is nonreference nodes – Node 1 and Node 2. The above mentioned **nodal diagram **creates a clarity in electrical circuit.

Calculate the nodal voltage for the circuit in the example below. The nodal voltages also play a vital role here.

The following circuit has three nodes, one of which is a reference node and the other two nonreference nodes, such as nodes 1 and 2.

**Step1:**

Node voltages are denoted with the letters v1 and v2 in step 1, and branch current directions can also be marked about the reference point nodes.

**Step 2:**

Apply Kirchoff’s current law to two nodes, such as nodes 1 and 2, in this stage.

When the circuit as mentioned above node 1 is subjected to the Kirchoff current law

i1 =i2+i3…… (1)

Likewise, at node 2

i2+i4 = i1+i5… (2)

**Step 3:**

When KCL equations are used with Ohm’s law

Using the elimination process

20 = 3V1-V2

60 = -3V1+5V2

4V2 = 80

V2= 20

When V2 = 20 is used as a substitution in equation (3), we obtain

20 = 3V1-V2

20 = 3V1-20 => V1 = 40/3 = 13.3 V

Consequently, the** definite node voltage** such as v1 = 13.33 V & v2 = 20 V is observed.

Similar calculations can be made for **nodal analysis with voltage source**.

A voltage source linked between the two non-reference nodes forms a generalized node. The specific node is referred to as the super node.
