Sodium Lamp with Power Supply

Code: PHEE0009

Solar Cell Unit

Code: PHEE0011

With motor, unit capable of rotating a small propellor, mounted on mini motor to explain conversion of solar energy into mechanical energy.

Mounted Motor for Solar Cell

Code: PHEE0013

This is a small low consumption electric motor on a base specially designed to run directly from the output of the solar cell and to illustrate the direct conversion of light energy to electrical and hence to mechanical. The motor spindle carries a simple pulley, 16 mm. diameter, and is capable of raising a mass of at least 4g. when powered by the solar cell.

Photo Electrical Cell Unit

Code: PHEE0015

Mounted on base, colour coded sockets, with circuit diagram printed for demonstration.

Photo Gates & Timer

Code: PHEE0017

These pair of photo gates is housed in tough moulded cases giving them excellent durability. The lamps operate on 6Volts with a special built in circuitry which prevents lamps from damage in case higher voltage is applied accidently. The photo gates can be connected by 4 mm. sockets to a timer and power supplies.

Electrical Whirl

Code: PHEE0019

For demonstrating the effect of electric discharge from points. The apparatus has a 60mm diameter, Three-pointed star wheel with all the points curved in one direction. The wheel rotates freely on a pivot point mounted on a short stand and the stand is provided with a 4mm connection socket on its round moulded base.
