In certain applications, the overall speed may be dependent on the RAM. If you have a fast CPU but very little RAM then your performance will be slowed.

The voltage on the control grid in a triode controls the current flowing from the cathode to the anode. When the grid goes negative, the tube is said to be cut off and no current will flow. When it goes positive, current starts to flow. As it goes more positive, more current flows. At some point, increasing the grid voltage won't cause any more cathode-to-anode current (plate current), and we call that saturation. We have to decide what to set the grid voltage at, and that is what we call biasing the tube. (We need to bias it.) Where do we want the tube operating with no signal applied? What kind of circuit is it in and how are we going to operate it? Class A, class B, class C or class AB? If a triode is set up with the grid negative all the time, no plate current will flow. If we set it up so that the grid is negative a little bit, then the input signal will have to go positive enough to overcome this voltage before plate current will flow. During the negative portion of the input signal, the tube will be cut off. Remember that it will only have plate current for a portion of the positive half of the input signal when the input voltage exceeds the "set" voltage on the grid (the bias voltage). This means that the amplifier will be operating class C. The class C amplifier operates for less than 180 degrees of the input signal.

a phase is like a part of your life when you have somthing for somthing example: when your twelve you want a game realy bad or when your four you want a toy tricycle but soon even if it happens you lose momentem that's a phase.

The Wembley stadium has a movable roof and this depends on a hydraulic system to move the huge cover. The retractable roof allows the sunlight cover to be monitored and that allows the grass to grow.

The RC circuit can reduce the phase shift between the voltage and current in the power line. The phase shift is caused by the inductance of the motor. The phase shift between the voltage and current in the power line causes problems due to the presence of so called imaginary current or power that does no work but must be supplied by the power source.

A proximity switch operated when you bring your hand or finger close to it. That's what's in lamps that turn on when you touch the base of the lamp. A photo switch operates when light shines on it. That's what's on streetlights that turns them on automatically after dark.

A CREE LED torch is like a normal battery powered torch, only using some newer features. The most important is the LED (Light Emitting Diode) invented by a American company named CREE. CREE LED's are mostly known for their efficiency. They are normally around 5 times more efficient then a Halogen light of the same spec.

The artificial eye works by filling in the place where your natural eye would have occupied. This eye does not function but looks realistic serving cosmetic purposes.

Thermal analysis are used to prevent the electronics circuit being damaged, such as heat sinks are used to absorb the heat which is created by the components to protect the sensitive components

You can test for voltage in a circuit with the help of voltmeter or multimeter (analog or digital (DMM) ). Vikas Pratap Singh NIT Kurukshetra vps3361@gmail.com

Synchronous motors are those that run only at Synchronous speed ie.. constant speed.

NORMALLY UTILITY SERVICE VOLTAGE ARE NOT STABLE AND THE WORST THAT COULD HAPPEN IS TO BURNOUT OUR SENSITIVE EQUIPMENT OR APPLIANCES DUE TO OVER AND UNDER VOLTAGE AND FREQUENT FLUCTUATIONS. IF YOU ARE USING OLD BUT SENSITIVE APPLIANCES THE BASIC SOLUTION IS TO USE AUTOMATIC VOLTAGE REGULATOR. NOWADAYS MANUFACTURERS SOLVE THIS BASIC ISSUE BY PRODUCING AUTOVOLT INPUT RANGING FROM 90V TO 260V AND CAN BE USED WITHOUT WORRIES IN EITHER 110V OR 220V SYSTEM.

They are widely used as voltage amplifiers (ie. In the initial stages of public address systems) because of their excellent audio-fidelity over a wide range of frequency. However because of poor impedance matching this type of coupling transistor circuits is rarely employed in final stages

A squelch circuit turns off the audio input to the speaker when there is no radio signal being received. This stops the speaker from producing annoying noise when no radio signal is being received.

A capacitor meter measures the value of a capacitor in pf (picofarads), nf (nanofarads), uf (microfarads) or even farads. There are a million uf in a farad, 1000 nf in a uf, and 1000 pf in a nf. A farad is a very large amount of capacity. The capacity tells you how much energy the capacitor can store from a voltage source.

It's called back EMF or reverse EMF. The EMF is electro-motive force, or voltage. What is happening is that the original current flow creates a magnetic field. That field then induces a voltage that opposes the original voltage that is causing the current flow. This back EMF "resists" the original voltage's efforts to cause current flow. If the created magnetic field did not oppose the original "efforts" of the voltage source to make current flow, then it would aid that voltage to make current flow. We would then get something for nothing and perpetual motion would be possible. We can't do that.
