How Solar System Works? Learn by Animation The circuit illustrated here is used as Solar Cell. You can get plate from your old faulty solar calculator. Carefully dissemble plate with out tearing its 2 wire. Connect both wire to a LED through a switch. When Solar Plate is kept in Read more…

Rectifier

LESSON ON HALF WAVE RECTIFIER / FULL WAVE RECTIFIER / BRIDGE RECTIFIER A Rectifier converts  AC (Alternating Current) in to DC (Direct Current ). Generally Diode is used as rectifier.  Rectifier uses the property of Diode( semi-conductor device)   to allow flow of current in only one direction.         Read more…

Magnetic Switch

Here is a simple Electronic Switch which can be operated by any Magnetic Field.  With little modification It can serve purpose of REED Switch just by adding a Relay Module. It can not directly drive electrical loads since their output drive capabilities are very small around 10 to 20mA, in that Read more…

Dynamo

Learn to make a AC Generator Simple Dynamo experiment This experiment shows Magnet +conductor+Motion=Current Make a coil of fine insulated wire wound on a plastic or cardboard tube. Connect the ends of the coil to a DC milliammeter or galvanometer (for demonstration purposes!). A center-zero meter is preferred for this Read more…
