What is meant by the term source?
usually power source where power comes from logic gates outputs are commonly called source or sink say the power source to the package is positive (VCC is +5) to call the output a source we would use an NPN transistor with the collector connected to +5V the base goes to the logic the emitter is the output terminal the output is the source of +5v sink output would have the emitter grounded base to logic the collector is the output so the output will sink positive voltage to ground A BUFFER usually has two output transistors one for source one for sink and can do either or both
How do you install an in ground swimming pool skimmer?
They are usually attached with a hose to vac source & float on top.
78xx regulater as a constant current source?
The 78xx regulater can be used as a constant current source, by connecting the output to the input side of a series resistor, and the "ground" to the other side of the resistor. Do not connect the "ground" to real ground - leave it floating.Since the 78xx maintains a constant voltage differential between output and ground, there would be a constant current through the resistor.
A receiver requires 10nW as input power if all the system losses add up to 50dB then how much power is required from the source?
here, the power required by the receiver is the output power and that required from the source is input power. Gain in dB=10 log(output power/input power) we have, loss in dB = -gain in dB = 10 log(input power/output power) or, 50 = 10 log(input power/10nW) or, anti-log(5) = input power/10 nW so the power required from the source is antilog(5)*10nW = 1 mW
When a transistor is required to match a 100W signal source with a high impedance output circuit then the connection that would be used is - a Common?
common base
What is Sink and source mode of transistor?
Source mode at output provides safety than sink at output
Is projector is an input or output device?
Output. It is taking data out the source (computer etc) and displaying it.
What is the output impedance of a constant voltage source and constant current source?
The output impedance is z= V/I, the ratio of the constant voltage and the constant current source.
How do you preview PHP source output?
The only true form of previewing PHP source output is to run the PHP script in question.
Use of transistor 7812?
7812 is not a transistor. It is a three lead voltage regulator integrated circuit. Its maximum input voltage should be near 35 volts. The minimum input voltage should be near 14 volts. The output will be 12 volts.
What is the output impedance of common source amplifier circuit?
The output impedance of a common source amplifier circuit is typically high. This is because the common source amplifier uses a resistor to provide biasing, which results in a high output impedance. However, this can be mitigated by using a current source instead of a resistor for biasing.
What does tcca 90 do in a swimming pool?
It is a source of available chlorine.
