Diode : one way street

Diode is a semiconductor device having two electrodes. It is mainly made from Silicon or Germanium.
Diodes have polarity. A diode has two terminals, the positive terminal is called anode and the negative terminal is called cathode. These terminals can be identified as there is a circular ring on the cathode and the terminal without ring is anode.

Sign language of circuit diagrams

We will try some exciting circuits in the coming blogs. The crucial skill of interpreting circuit diagrams cannot be ignored. Similar to preparing a food recipe, a crucial skill is to know the ingredients, proportion thereof and when to add in the making process as well as a power source to be low or high flame, microwave etc.[..]

LED Display

In this activity, we are joining LEDs in parallel connection by soldering to make an interesting display. Parallel connection means the positive terminal of all the LEDs will be joined together and all the negative terminals will also be joined together with the help of soldering using connecting wire.[..]

Series Circuit : A continuous chain/ Hum Sath Sath Hain

In an electrical circuit, there are basic two ways in which components can be connected. One way is series connection.
In series connection, all the components are joined to each other like a chain in a single line style.
Current just has one path to flow from. Current flows from the source[..]
