what is the other name of common emitter amplifier

Where can I get copy explaining what the symbols mean on a sperry multimeter and how to use them.

Assuming galvanometer has zero or negligible internal resistance. If u connect resistor R>>RL(Load resistance) and connect it parallel to RL, it will hardly cause any change in voltage across load resistance. Suppose small current Ig goes through galvanometer. Since galvanometer have zero internal resistance,

Voltage across RL = Voltage across R = IgR

The main advantage of ECL over TTL is speed.

2.43 GBits/s

pata nahin yaar main bhi dhoond raha hoon

An Silicon Controlled rectifier is most utilized in switching applications. For example: discharging a capacitor. Because a SCR stays on until a certain voltage between the collector and emitter drops bellow a certain level, the SCR will stay on when triggered until the capacitor is empty.

about ~30v

A PLL is different than a VCO. Each has its own use.

Actually a PLL (Phase Locked Loop) contains a VCO (Voltage controlled oscillator).

A VCO is an oscillator whose frequency is related to an input voltage. You can use it when you need a varying frequency that is controlled by a varying voltage. But it is not great at outputting a consistant exact voltage because it is very sensitive to its environment (e.g. temperature).

A PLL will "lock" its output frequency to some input frequency. So it can oscillate at a frequency that is controlled by an input oscillator. Not too useful if the output frequency is the same as the input. But the output frequency can be divided before it is compared to the input. This allows the output frequency to be higher (some multiple of) the input frequency. Once a PLL is "locked on" to an input frequency it can be very stable.

Voltage and current are two different things.

Voltage is the electric potential difference between two points. Expressed in volts, it is also joules per coulomb.

Current is the charge flow past a point. Expressed in amperes, it is also coulombs per second.

You can relate voltage and current using Ohm's Law, which states that voltage is equal to current times resistance.

Resistance is, therefore, equal to voltage divided by current. Using base units, resistance is equal to joules per coulomb divided by coulombs per second, which simplifies to joule-seconds per coulomb squared. That is a difficult unit to write, so we just use ohms as the unit.

Read about logic ring counters.

I am not to sure about Static Ram but in CMOS RAM, 1GB of RAM would contain about 137438953472 transistors because 1 bit of CMOS RAM contains 16 Transistors, 8 bits in a byte and 1073741824 bytes in a gigabyte.

I am 100% sure about this and these are just estimations.

Static RAM uses about 6 times as many transistors as dynamic RAM for the same amount of storage. Dynamic RAM uses 1 or 2 transistors per bit in typical implementations. Add to this transistors for address decode, bus interface, etc.

A voltage buffer is a circuit that will buffer a source from an output.

it all depends on its open loop gain or crossing the zero db point at slope less the -1db

ZENER DIODE IS MADE TO REVERSE BREAK OVER AT A CERTAIN VOLTAGE the break over knee is not exactly sharp especially in low voltage zeners. and p-n means positive and negative junction

Motion detectors have had a massive impact on today's society. Motion detectors have made life easier for those who are very busy for example.

Yes, but the transformer must have both the hot and neutral to work as designed. A auto-transformer is not a variable resistor that could reduce current/voltage by a change in the resistance which could be used in the hot and or neutral wire. An auto-transformer is designed to have the hot wire and neutral on each end of the winding with a variable tap in between. The resistance of the transformer and the inductance will effect the circuit to a limited way if placed in the neutral but this effect will not vary the voltage over the full range, the amount of voltage reduction will vary with the load's current draw, see ohms law. Neither a resistor or a auto-transformer connected in the neutral line only will increase the voltage above the level of the input like a correctly connected auto-transformer . Stanley

Usually copper, sometimes gold or silver.

Once a circuit is designed the means to connect all devices comes under a layout on a PCB printed circuit board. the layout means locating and connecting all of the designed circuit.
