Three Step Inductor
Description
This three step inductor consists of a coil of enamelled copper wire wound over an insulated spool.
The coil consists of 4 layers of 200 turns each. The tappings at 200, 400 and 800 turns are brought out at 4 mm sockets.
The output inductances at these tappings are as follows.
No. of turns Resistance 200, Inductor 0.3 mH, Resistance 0.6Ω
No. of turns Resistance 400, Inductor 1.2 mH, Resistance 1.2Ω
No. of turns Resistance 800, Inductor 5.0 mH, Resistance 2.6Ω.
One can easily change the inductor value of the instrument on just inserting a soft iron core inside the bobbin

Earth, Neutral And Live Board Demonstration
Description
This apparatus is an effective demonstration of how the earth wire and fuse act together to protect both the user and the appliance. When the appliance is connected correctly and the LEDs in the appliance will illuminate to show the appliance is working. A fault is then demonstrated by swapping the live wire from inside the appliance to the case to show either the fuse melts (protecting the user and appliance) or in the case of no earth wire, the LEDs illuminate to indicate the passage of current through the person to ground. The fuse is easily visible and can be seen to ‘blow’ when a fault occurs.The unit is supplied with 10 m of fuse wire and full instructions. A 12 V DC power supply is required. Connections are made via 4 mm shrouded sockets.
