Amr Saleh


My name is Amr Saleh. I'm a Teaching Assistant in Electrical Power and Machines Engineering, Ain Shams University.

Through my career,  I teach many courses related to different topics of electrical power engineering including Power Systems , Power Electronics , Electric Machines, High Voltage and also Electric controls and protection.

I gained knowledge in these areas of Electrical Engineering during my undergraduate studies and my Masters degree, as well as during my professional career, and am excited to teach about them in Tutorialspoint. 

In fact, I love teaching electrical engineering topics and I like both the theory behind a topic as well as real-world applications in very simple way to make my students understand the complete picture of the topic.

My goal is to deliver my knowledge about electrical engineering to my students.
