i dont know how to ensure that two diode are conducting .my professor said to remove the diodes and find the current direction ,if the current direction of branch matches with reference current direction of diode then it is on else it is off.Is that way to ensure the conduction of diode or any...
i want to control my pc mouse action from arduino board ,i already did this with help of matlab. But now i want to do this without any helping software ,i want it like plug and use. Is there anyway to do so?
i am studying bjt amplifiers,i am often getting through impedance of input and outputs . Its messing up with me
example:common collector configuration have high input impedance and low output impedance
does that input impedance is impedance between the terminal( base and collector)?
it is also...
ohh ,kvl that is that magic word i missed,thanks .
Now, 3v dc source is replaced with forward biased pn diode
Vo = 5 sqrt(2) sint (wt) -0.7V
am i right?
i have attached my circuit and corresponding waveform,i don't even know what my attached circuit is called as.i have 5vrms ac source c, 3v dc source ,some k ohm resistor , all are connected in series.my output waveform look like its shifted down.what operation actually going on there and how the...
The transfer characteristics of zener and pn diode looks same in reverse bias, i have asked few why in many rectifier circuits zener is used.i got answer like, it wont burn up in high reverse current like pn diode . why zener is special than pn diode.
okay another question which is slight away form this topic,sorry if the question is very basic
output of microphone (transducer) is voltage signal(voltage varying with time)
if the power amplifier want to amplify the current of this signal ,how could it be, because output of transducer is...
voltage amplifier does voltage amplification
current amplifier does current amplification
Is there something like power amplifier or power amplifier is just same as current amplifier?
i am sailing in boat moving 3 units in north moving 4 units in east having 3+4j as vector now i want to rotate it to 90 degree counter clockwise so i just multiply by i.Then i get the answer ,but i want to know it can be done in harder way,i mean how to do same rotation with using complex plane...
The voltage in a circuit is 45 + j10 volts
The impedance in one part of a series circuit is 45 + j10
The current in a circuit is 45 + j10 amps
what is the 10 represent in each case?
i am so much confused with complex exponential.so i need to break that down into basic and rethink about it
1) why do we need complex number why not we stay with real number alone and what are the impossible become after possible after discovery of complex number.Thank you in advance
