# What is kirchhoff’s laws ? for magnetic circuit & How relate to electric circuit

These two laws allow the Currents and Voltages in a circuit to be discovered, i.e. the circuit is claimed to be Analysed, and the fundamental procedure for utilizing Kirchhoff’s Circuit Laws.

## Kirchhoffs Laws for the Magnetic Circuits :

Similar to the Kirchhoff’s laws of electric circuits, there are Kirchhoffs Laws for magnetic circuits. They are stated as follows :-

• Kirchhoff’s first Law (Kirchhoff’s current law of electric circuits)(KCL)
• Kirchhoff’s Second Law (Kirchhoff’s voltage law of electric circuits)(KVL)

### Kirchhoff’s Current Law Of Electric Circuits (KCL)

This law states that the total flux directed towards a junction is equal to the sum of magnetic fluxes directed away from that junction. Kirchhoff’s first. Law is analogous to Kirchhoff’s current law of electric circuits.

### Kirchhoff’s Voltage Law Of Electric Circuits (KVL)

This law states that in any closed magnetic circuit the algebraic sum of the product of the magnetizing force (H) and the length of each part (1) of the circuit is equal to the resultant m.m.f. Kirchhoff’s second law is analogous to Kirchhoff’s voltage law of electric circuits.

## DC Circuit Theory Common Terms :

• Circuit – a circuit is a closed loop conducting path wherein {an electrical} current flows.
• Path – a single line of connecting elements or sources.
• Node – a node is a junction, connection or terminal inside a circuit had been two or extra circuit elements are related or joined collectively giving a connection point between two or extra branches. A node is indicated by a dot.
• Branch – a branch is a single or group of elements reminiscent of resistors or a supply that are related between two nodes.
• Loop – a loop is a straightforward closed path in a circuit wherein no circuit element or node is encountered greater than once.
• Mesh – a mesh is a single closed loop series path that doesn’t comprise every other paths. There aren’t any loops inside a mesh.
