What is the phase relationship between the input and output signals of the common collector amplifier?
Common emitter is the only transistor configuration that has an 180 degree phase difference between input and output. Common base and common collector outputs are in phase with the input.***********************************That is incorrect.The output of the common emitter is inverted, there is no phase shift.
What contributes harmonic distortion in amplifier?
+ve feedback
How do you connect the parts of a simple electric circuit together so that the light bulb lights up?
Simply connect the -ve of the bulb to -ve of the battery and +ve of bulb to +ve of battery using an electrically conductive wire, the bulb will light automatically.
Why the output waveform at summing amplifier is out of phase of 180 with input signal?
Because as the signal voltage increases on the base, the base current increases this causes the collector current to increase, this decreases the voltage drop Vc to ground. As the base voltage decreases the base current decreases causing the Collector current to decrease, increasing the voltage drop Vc to ground. i think dis ans will clerify d doubts of students... ... in CE config.. as Vo=Vcc-Ic Rc nw as Vcc is const. v cn say Vo is directly proportional 2 (-Ic Rc) so nw when d base voltage is increased Ib will inc. thus, Ic will inc. cuz Ic=beta Ib thus Ic Rc drop increases... as Vo is prop 2 -Ic Rc thus, Vo will decrease...thus d curve for d +ve half cycle in which Ib is increasing drawn in 180 deg phase showing Vo is dec. n vice versa 4 -ve half cycle... nw in CC... as d o/p is taken frm emitter... Vo= Ie Re so der's no -ve sign..n for d +ve cycle Ie will incr(dat's leakage current) as der's no-ve sign it'll b in phase wid i/p..hence no phase shift as leakage current doesnt incr. so much thus,d o/p voltage Ie Re doesnt inc much thus, d o/p doesnt amplify much thus dis config knwn as emiter follower... nw in CB,... d I/P is appiled at emitter n o/p is taken frm collector... so, 4 d +ve half cycle d Eb junc will b more FB thus causing incr. in Ib n thus, in Ic... so inc. in Ic causes inc. in o/p voltage..n during -ve half cycle d junc will b less FB so o/p voltage will b decreasing..hence der's no phase shift... for any other help.. cont.- shrey.dhingra51@gmail.com
What is the difference between parallel and cereal circuits?
in the series circuit elements are one behind the other ie +ve terminal of one element is connected to the -ve of other element of the circuit whenever in parallel circuits the elements are parallely connect ie all +ve terminal are connected at a point and all -ve terminals of the elements are connected at a point.

How can electrons flow through base collector reversed biased region in transistors?
collector base is reverse biased (connect n region to be +ve terminal &p region to - ve terminal .due to forward biasing at emittor base juntion electrons follow from emittor to base .
What do Einstein and Newton have in common?
pacha ve
What are the uses shridhar acharya's formula?
ve can find out quadratic equations
Formula for calculating distribution coefficient kd in size exclusion chromatography?
Kd = (Ve - Vo)/(Vt - Vo) Ve = elution volume Vo = void volume Vt = volume total
What is the chemical formula of cesium hydride?
Caesium hydride. CsH . ionically it is 'Cs^+' & 'H^-'
What is three divided by negative three?
Division by negative numbers follow the same rule as multiplication. That is, (-ve and +ve) or (+ve and -ve) make -ve (-ve and -ve) or (+ve and +ve) make +ve. So the absolute value of 3/(-3) is 1 and the sign is (+ve and -ve) = -ve so that the answer is -1.
What does the electronic term Vb mean?
Base voltage in a transistor. There is also Vc (Collector voltage), Ve(Emitter voltage), Ic(Collector current), Ib(Base current), Ie(Emitter current), Vcc(Supply voltage), and Hfe (Forward current gain)
How do you connect 5 LED rebel star?
Have a common ground and separate the +ve to each of the LEDS
