Experiment for question(2)
substance required
An AC stepdown transformer of 6 volt
Two PVC pipes 20 cm. length,of diferent radius.
28 gauge insulated copper wire 100 grams.
22gauge insulated copper wire 100 gm.
A diode(No.1408)
A L E D.
procedure
Wound 28 gauge wire on larger radius pipe in 250 times(primary),wound 22gauge wire on another pipe in 350 times(secondary) and it is connected to LED.
Solder diode to output of transformer and connected to primary coil.
Transformer is to be connected to AC mains.
Slowly secondary pipe is inserted in primary pipe.
observation
The LED will glow.
