WORKING PRINCIPLE A voltage is applied across the anode and cathode. Current flows from cathode to anode through the organic layers. Electrons flow to emissive layer from the cathode. Electrons are removed from conductive layer leaving holes. Holes jump into emissive layer . Electron and hole combine and light emitted.

4. 4 Introduction • A pH meter is an electronic instrument used for measuring the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of special measuring probes (a glass electrode and a reference electrode) connected to an electronic meter that measures and …
There are construction works that require digging in-depth to move large amounts of material, so an excavator is necessary to perform such work. From operations in sewers, water pipes, wiring, through the construction of urban complexes, roads, highways, and paving, excavators are really useful to do deep work with high perf…

3. Therefore, a synchronous motor can be made to carry the mechanical load at constant speed and at the same time improve the power factor of the system. Synchronous motors are generally of the salient pole type. A synchronous motor is not self-starting and an auxiliary means has to be used for starting it. We use either induction motor principle or a …

• Principle of Operation A rotating field is set up in the stator when a 3- Phase supply is given. The stationary rotor cut the revolving field and due to electromagnetic induction an e.m.f. is induced in the rotor conductor. As the rotor conductor is short circuited current flows through them. It becomes a current carrying conductor in ...

8. In a three phase induction motor, the induced emf in the rotor circuit depends on the slip of the induction motor and the magnitude of the rotor current depends upon this induced emf (electromotive force). When the motor …
14. Negative Phase contrast: • The background light is phase shifted -90° by passing it through a Phase shift ring. This eliminates the phase difference between the background and the scattered light. • To further increase contrast, the background is dimmed by a gray filter ring Positive phase contrast: • the background light is instead phase shifted by +90°.
