Seeking Electronics Project Tutorials for Beginners

[Hyperspace2]

I am first year electronics engineering student.
I have been looking to do electronics projects . So I am looking all over internet to find the good electronics project tutorial. Most of them I found was useless. They give schematics and tell how they work and they stop there

for now I have been thinking, aren't there the sites which teaches how to calculate the current and voltage in each part of circuit , why they are use there (with analogies at basics)

Please help me find the sites that gives many practice circuits and calculation problems thus imparting knowledge of calculation and desighning. It must have the practice circuits from very simple and heading towards complexity

It should teach the begineers in very preliminary way. Did you understand what I mean?
Thanks for reading . Hope you will help me.

have a look here for a reasonable tutorial

Remember ...
1) the voltage drops across each component (element) in the circuit... the sum of the voltage drops across each component will equal the total voltage across the circuit.

2) the current remains constant throughout the circuit... that is take a circuit consisting of 3 series resistors R1, R2, R3, connected across a battery and a 2 amp current flowing. It doesn't matter where in the cct you measure the current, it will always measure 2 amps...
between the battery and R1... or between R1 and R2 etc etc

read and work your way through that tutorial and see if you understand the reasons why :)
