Engineering from Scratch
Hello there. This site was made with one purpose: to collect an advanced course worth of material in Electronic and Electrical Engineering. It is available for anyone who needs it for free.
University Curriculum – Based on uni material, students’ notes and industry experiences
Blog Type Approach – We regularly upload new materials.
Absolutely Free – Sharing is Caring
Skilled people are needed all around the world to figure out the issues on our planet. Billions of us are waiting for someone to come up with a magical fix or cure. Why not work on our skills & knowledge and see how we can contribute? Barack Obama said it once:
‘Change will not come if we wait for some other person or some other time. We are the ones we’ve been waiting for. We are the change that we seek.‘

About the Synchronous Reactance Model, phasor diagram, leading and lagging power factor in generators/motors due to over/under-excited field current.
Induction vs Synchronous Machines
Induction Machines, that always lag behind the synchronous speed, are a simpler from of Synchronous Machines. Let's go into bit more detail about them.
3-Phase Power & Distribution
3-Phase Power is distributed either by a Delta or Star configuration. This topic focuses on the derivation of power, power factor and efficiency.
Transmission Lines & Electricity Distribution
Power Plants generate electricity that is carried to the cities by Transmission Lines. Although, this is is a little complicated due to ohmic losses.
