... in CE config.. as Vo=Vcc-Ic Rc nw as Vcc is const. v cn say Vo is directly proportional 2 (const.-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 (const.-Ic Rc) thus, Vo will decrease for inc. in Ic...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 less FB thus causing dec in Ib n thus, in Ic... so dec in Ic causes inc. in o/p voltage(cuz Vo=const.-Ic Rc)..n during -ve half cycle d junc will b more FB(inc in Ic) so o/p voltage will b decreasing..hence der's no phase shift...

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.
How do you derive three phase single way?
3 phase /sqrt(3) * 30 degree phase shift = single phase.
How many diodes can be used in center tap type rectifiers?
There are two diodes in a standard center tapped configuration of a rectifier. This is per phase, so if you had a three phase system, each winding having a center tap, all of which are connected together, you would have six diodes.
What is phase angle between line and phase currents in delta?
A delta connection should cause a 30 degree phase shift. It is necessary to know the configuration to tell whether this is +30 or -30 degrees.Also, if you invert the connection, you can end up with [-30 + 180] 150 or [30 + 180] 210 degree phase shifting.I've seen one transformer that had a delta connection that was phase shifted 150 degrees, but this is definitely NOT the norm.CommentSince the current is determined by the load, the answer to this question is that it depends upona. the nature of the load (resistive, R-L, R-C, R-L-C), andb. whether the load is balanced or unbalanced.In other words, it depends....
How do you get phase shift in Hartley oscillator?
basicaly the two inductors work as an autotransformer,providing a phase shift of 180 degree
Phase-shift oscillator using pnp transistor?
A phase-shift oscillator using a PNP transistor consists of an RC network in the feedback path, a PNP transistor biased to operate in the active region, and a network of resistors and capacitors that provide the required phase shift for oscillation. The RC network introduces a 180-degree phase shift at the desired frequency, and the transistor provides the additional 180-degree phase shift needed for sustained oscillation. By properly selecting the values of resistors and capacitors, along with biasing the transistor correctly, a stable sinusoidal oscillation can be achieved.
Why CE configuration of BJT transistor gives 180 phase shift?
when the switch the emitter-base junection is an opnd circut and heance the value of input or base curent is zero.
Why does a phase shift occur in a ce transistor?
In any transistor circuit , there is a phase shift. It takes a finite time for the controlling signal, usually on the base connection, to have an effect on the circuit and cause a change to the output. The shape of the signal remains but it is shifted in time (phase). The difference varies by configuration. It can be as much as180 degrees if the circuit is inverting the signal. The addition of passive components add to the shift.

Why Phase Shift on transistor amplifier?
because that's how God intended the way of the world to be..
How transistor produce 180 degree phase shift?
In the common emitter configuration, a class A amplifier, an increase in base voltage (the input) leads to an increase in base-emitter current which leads to a proportionately larger increase in base collector current. That pulls the collector towards the emitter, which decreases the collector voltage. Since the collector is the output, this configuration is an inverting amplifier.
What degree is xenon at normal phase?
The answer depends on what is meant by "normal phase".
What is Dy11y11?
Postcode for Kidderminster in the West Midlands, UK. Also a vector group (connection configuration) of a 3-phase transformer.D - Means Delta Wound Primary Y - Means Wye (Star) Wound Secondary 11 - Is the phase shift between the two windings. The 11 refers to 11 on a clock face, hence 30 degrees.
How do you derive three phase single way?
3 phase /sqrt(3) * 30 degree phase shift = single phase.
Is there any phase shift between input and output in cc configuration?
No, in a common collector (CC) configuration, the input and output signals are in phase with each other. This is because the output voltage is taken from the collector terminal, where the collector current flows without any phase shift.
How many diodes can be used in center tap type rectifiers?

What changes mechanical energy into electrical energy that can be transported through the power grid?
A three phase alternator (sometimes incorrectly called a generator or AC generator) is a device that changes rotational mechanical energy into electrical energy. The power grid transmits three phase electrical power (usually in Delta configuration) from electricity suppliers to local distribution systems; which then distributes the electrical power as either three phase Delta configuration, three phase Y configuration, two phase, or single phase power depending on the needs if the users.
