Common Emitter (CE) mode, or Class A operation, always introduces a 180 degree phase shift, i.e. it is inverting, whether or not you use PNP or NPN transistors.
In NPN, an increase in base voltage increases the collector current, which decreases the collector voltage.
In PNP, a decrease in base voltage increases the collector current, which increases the collector voltage.
They are both inverting.
When I say "increase" or "decrease" of voltage, I mean that "increase" means "towards the plus power supply".

What is Vector meter?
A vector impedance meter is used to measure impedance and phase angle, this is done by calculating voltage and current through an impedance and then calculating Z and phase angle with that, now there are two modes for operation i.e constant current mode and constant voltage mode.CONSTANT CURRENT MODERead more: What_is_vector_impedance_meter_explain_with_circuit_diagram
How will star and delta configured three phase induction motors perform as load increases?
Motors with star delta starter, starts with star mode, avoiding inrush of current for a relatively higher starting load, as the speed picks up, it goes to Delta mode with full phase voltage applied across the winding and continues to cater to the designed load.
Why common emitter configuration is preferred?
Reason: The common Emitter mode has voltage and current gain better than the other two configurations(CB and CC). i.e it has a current gain greater than that of CC mode and greater voltage gain than that of CB mode.

What is inverting and non inverting mode of op amp explain?
Inverting and non-inverting modes refer to the two primary configurations of an operational amplifier (op-amp). In the inverting mode, the input signal is applied to the inverting terminal (negative input), resulting in an output that is 180 degrees out of phase with the input, with a gain determined by external resistors. Conversely, in the non-inverting mode, the input signal is applied to the non-inverting terminal (positive input), producing an output that is in phase with the input and has a gain greater than one, also determined by external resistors. Both configurations leverage the op-amp's ability to amplify voltage signals while providing different phase relationships and gain characteristics.

How the polarity of a compound will affect on both normal phase and reverse phase mode chromatography?
In normal phase chromatography, polar compounds are retained more strongly due to interactions with the polar stationary phase, while nonpolar compounds elute first. In reverse phase chromatography, the opposite is true: polar compounds elute first because they have less interaction with the nonpolar stationary phase, while nonpolar compounds are retained more strongly.

How to change the mode on a bistec calculator?
press shift and then press mode, keep pressing if you didn't find the perticular mode
What does the sport mode button on a jaguar xk8 do?
The sport mode changes the shift points on the transmission.
Does need for speed shift have a free run mode?
No, sorry.
When an enhancement MOSFET operates in the saturation region?
Saturation mode is when the drain voltage is higher than the gate voltage, at which point the channel becomes very wide and there's a good amount of current flow. This is also called the active mode. In comparison to the linear mode, where the current increases linearly vs drain to source voltage, in the saturation mode increasing the drain voltage further won't affect the current flow, since it's already saturated. Please note that it's assumed that the gate voltage is larger than the threshold voltage, which will turn on the FET.
What is sport mode in automatic transmissions?
Sports mode changes both the shift points(increases the rpm) and the firmness of the shift(decreasing the amount of time it takes to shift gears), thus increasing acceleration performance of said vehicular object. :)
What is common mode rejection ratio Explain briefly?
common mode rejection ratio is defined as ratio of differential voltage gain to common mode voltage gain Common mode rejection ratio is the ability of the circuit to reject common entries like noise.
Why common emitter configuration is preferred?
Reason: The common Emitter mode has voltage and current gain better than the other two configurations(CB and CC). i.e it has a current gain greater than that of CC mode and greater voltage gain than that of CB mode.

What does the dodge stealth 'power' button do?
It switches from a fuel conserving mode to a more powerful mode. Basically it changes the shift time so when you gun it, it will only hit about 3-4000 rpm's then shift, compared to power mode where it will nearly redline giving you increased acceleration and power.
