you are jumping way too far ahead of the game it would seem.
I have previous!
You need to study from the start because it is a series of building blocks. Wikipedia may be a good place to start or there may be some video's out there.
You need to start with resistors and capacitors, inductors are the only other main passive, resistors, capacitors and inductors are THE 3 passive components that represent the 3 physical properties in nature regarding components. In time you will discover that the component called a resistor is not purely resistive, a capacitor is not purely capacitance, and inductors are not purely inductive. But to start you don't need to worry too much.
Then you move onto how these parts interact together, resistors form potential dividers and any mix of at least two will form a filter. finally the RLC filter arrives and this is where you learn that any part has all 3 physical properties but one will shine through over the others overwhelminly if the part is used under he correct conditions.
Then study diodes and transistors, both BJT's and MOSFET's, for now not too deeply, don't go into the physics.
Then you start on the building blocks of electronics like operational amplifiers.
You have to take it block at a time.
At the moment only use you can make of those boards is nothing unless you want to strip them of parts which is pointless if you are in a position to purchase parts.
