Basic Electronics Notes

## Node Voltage Method

Another alternate method of analysis of multiple loop circuits is called the node voltage method.

## Mesh Current Method

In the mesh current method, you will work with loop currents instead of branch currents. A branch current is the actual current through a branch.

## Maximum Power Transfer Theorem

A resistive load will abstract maximum power from a net work when the load resistance is equal to resistance of the network

## Ampacity Table

Ampacities of Insulated Conductors

## Lenz's Law

The direction of induced current may also be found by lenz's law which was formulated by Lenz in 1835.

## Kirchhoff's Voltage Law (KVL)

Kirchhoff's Voltage Law states that ''The algebraic sum of all voltages (source voltage and voltage drops) is equal to zero around a close path''.

## Kirchhoff's Current Law (KCL)

The sum of the current into a junction is equal to the sum of the current out of at junction.

## Insulation Resistance Test on a Transformer

Class 1 Transformer, Insulation resistance tests between each winding and earth

## Magnetism

Magnetism is a property of materials that respond at an atomic or subatomic level to an applied magnetic field.

## Magnetic Flux

The total number of magnetic lines of force of a magnet is called magnetic flux. It is represented by phi (ϕ) and its unit is Weber.
