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.
Operation of a commercial steam engine is well illustrated with this working model.
The extra large size unit is provided with a horizontal boiler with a whistle, safety valve, steam gauge, on metal base.
Operates on 220V A.C. 50 Hz.
To show conversion of mechanical energy into electrical energy.
Turbine with transparent cover, inlet and outlet tubes, directly connected to a dynamo. Fitted on base.
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.
