# What is dependent and independent voltage source?

## What is dependent and independent voltage source?

An independent voltage source maintains a voltage (fixed or varying with time) which is not affected by any other quantity. They are called dependent voltage (current) sources or controlled voltage (current) sources , and their usual symbols are shown in figure 1.4.

Why do we use nodal analysis?

We use nodal analysis on circuits to obtain multiple KCL equations which are used to solve for voltage and current in a circuit. The number of KCL equations required is one less than the number of nodes that a circuit has. The extra node may be referred to as a Page 4 reference node.

### What do you mean by dependent voltage source?

In the theory of electrical networks, a dependent source is a voltage source or a current source whose value depends on a voltage or current elsewhere in the network.

What are examples of voltage sources?

Nuclear, coal, natural gas, hydroelectric and wind power all use generators to generate voltage.

## Where is nodal analysis used?

We use nodal analysis on circuits to obtain multiple KCL equations which are used to solve for voltage and current in a circuit. The number of KCL equations required is one less than the number of nodes that a circuit has.

What is the basis of nodal analysis?

Nodal Analysis is based on the application of the Kirchhoff’s Current Law (KCL). Having ‘n’ nodes there will be ‘n-1’ simultaneous equations to solve. Solving ‘n-1’ equations all the nodes voltages can be obtained. The number of non reference nodes is equal to the number of Nodal equations that can be obtained.

### What are two types of voltage sources?

Types of Voltage Source Independent Voltage Source: They are of two types – Direct Voltage Source and Alternating Voltage Source. Dependent Voltage Source: They are of two types – Voltage Controlled Voltage Source and Current Controlled Voltage Source.
