Does anyone have a manual or something from where to learn the basics about circuit theory?Or give me a link (I prefer it to have some exercises based on the theory) from where to learn..Thanks..

Here you go; no excercises that I know of but it has a lot of good information.

Very basic:
Imagine a container with water.
The water is the voltage, and the more water, the higher the voltage. It can't go anywhere, it doesn't do anything on its own.
Therefore-
Connect a pipe to the container (downwards), the water flows. Hold your finger on the end, and the pressure you feel is the current.
Try the same test with a pipe of much smaller diameter and you will realize that the pressure (current) is less. That means, the diameter of the pipe forms a resistance to the water flow, it is a resistor.
Now let the water flow into a bucket. The amount of water you collect in the bucket within any fixed time is the wattage.
Now translated to electrics: Current (Amp) = Voltage (Volt) div.by Resistance (R)
Wattage (Watt) = Voltage (Volt) X Current (Amp).
A Capacitor is then a small container which you place somewhere in-between your pipe to level-out uneven water flow.
A switch is a valve which can shut the water flow on and off.
A relay is a valve that is driven by an electric magnet to turn off or on. A transistor is a contraption which needs very little water flow in order to trigger a large water flow.
Now you have the basic components explained....

probably wikipedia.org might be a good source.
