Engineering sector supports off-the-job technical qualifications
According to Semta, the not-for-profit employer-led body tasked with securing the sector’s skills pipeline, the new Institute for Apprenticeships policy of allowing off-the-job technical…
Periodic non-sinusoidal currents in linear circuits
Periodic non-sinusoidal currents and voltages are those that change in a periodical non-sinusoidal way. It may happen when the source is generating non-sinusoidal signals, and…
Transient processes in linear circuits
Transient processes in electrical circuits are the processes of transition from one work regime to another, that differ with parameters. Transient processes are caused…
Non-linear DC electric circuits
Non-linear electric circuits contain non-linear components. Non-linear electric components are characterised with non-linear volt-ampere characteristics, as depicted on the figure below. Non-linear components can…
Magnetic circuits
Magnetic circuit is a set of components, combined in one circuit, that create a magnetic field loop. In calculating magnetic circuits we must remember…
Is your small business ready to hire an apprentice?
Small businesses shouldn't be put off from employing an apprentice because of certain negative comments about the Government's apprenticeship levy. In this article, Laura…
Non-linear AC circuits
Non-linear AC circuits are AC circuits containing non-linear components. Nonlinear components can be resistive, capacitive, and inductive. Non-linear resistors can be inertial, and non-inertial.…
Optical and photoelectrical properties of semiconductors
Light absorption When light penetrates the semiconductor, it starts the process of exchanging energy with crystalline lattice. Let us determine I as a light…
Thermoelectrical phenomena and Hall effect in semiconductors
For semiconductors, as for metals, there will be potential differences on the contacts with different temperatures, and an electrical current will occur between these…
