For use as a water turbine to drive a generator producing electricity or for use as a pump driven by a motor and raising a head of water to produce potential energy.
The rotor has eight 'bucket' blades and is housed in a block turbine chamber with a clear Perspex front.
Two inlet tubules (for turbine and pump operation respectively) and one outlet tubule are provided and the shaft carries a 15 mm.
diameter pulley.
With driving belt.
Determination of charge on a electron by measuring a known distance on the basis of number of times of fall under gravity and of rise in uniform vertical electrostatic field in a series of charged oil drops.
For showing the conversion from electrical energy via mechanical, to potential energy by winding up a weight on a cord.
One end of the 6mm.
steel shaft carries an aluminium 'V' pulley 56 mm.
diameter, and the other end is fitted with a cord anchoring collar.
Supplied complete with driving belt.
A model of the simplest form of D.C. electric motor, having 2-pole armature wound with enamelled copper wire and a permanent magnetic field provided by a removable bar magnet.
A disc-type commutator is incorporated and external connection to the phosphor-bronze bushes is by means of a pair of 4 mm. sockets.
The motor will operates on 6-8 Volts D.C.
To show the forces which can be exerted during thermal expansion or contraction.
Comprising a heavy cast iron frame 340x120x100mm with slotted end pillars to carry a stout iron bar.
The bar is threaded at one end for a large tensioning nut and has holes at the other end to accommodate the cast iron breaking bars.
Supplied complete with ten breaking bars.
