Practicing electric schematics and drawings online?

[Hrvoje]

Hello everyone.

Is there a place online where there are electric drawings and schematics with descriptions of sequence of their work? Like a step-by-step on what's going on in the circuit. I really need to practice schematics reading and then check if I got the circuit right.

How about a systematic approach to practical electrical engineering like connecting relays and contactors, basics of fault finding, using voltmeters to locate a break in the circuit, instructions on calibrating different switches, using barriers, dissembling of AC motors etc.?

Thank you in advance.
