Circuit theory is important for electrical engineering, physical science, networking. Circuit theory is the fundamental of electrical engineering. Every electrical engineering students should have clear concept about circuit. We transfer electrical energy one place to another through circuit. In our houses we use different types of circuit for using fan, bulb, iron, fridge, … [Read more...] about What is Circuit Definition and Basic of Circuit

## Mesh Analysis Calculations, Steps, Examples Step By Step

Mesh analysis is a circuit solving procedure using mesh current. In nodal analysis we apply KCL to find unknown voltages. But here using KVL we will find unknown currents using this method. We will use mesh currents instead of element current. Mesh analysis reduces the equations getting current. Nodal analysis can be applied in each general circuit but mesh analysis cannot be … [Read more...] about Mesh Analysis Calculations, Steps, Examples Step By Step

## Nodal analysis with voltage sources

Nodal analysis is the method to determine voltage or current using nodes of the circuit. In nodal analysis we choose node voltage instead of element voltages and hence the equations reduces in this process. We have to consider voltage source is not in this circuit. We have to solve a circuit with n nodes without voltage sources. To solve a circuit using nodal analysis method … [Read more...] about Nodal analysis with voltage sources

## Voltage source to current source conversion

Conversion of voltage source into current source is possible when a voltage source is equal to current source. Figure 1 is a circuit of constant voltage source and figure 2 is a circuit of constant current source. If the two circuits are satisfied electrically the same way under all condition then we can convert voltage source to current source having no doubt. … [Read more...] about Voltage source to current source conversion
