Where does the input power go when the mechanical output power is zero?

either to friction (heat, sound, light) or to internal mechanical changes
Another AnswerPower doesn't 'go' anywhere! Power is simply a 'rate': the rate at which the machine is doing work. If the machine isn't doing work by supplying a mechanical load, then it's output power is zero. However, energy still has to be provided to overcome the losses due to heat transfer from the machine, friction, windage, etc. The rate at which this energy is supplied to the motor is the power of the machine off load.

What gate the output will be low for any case when one or more input are zero?
An inverter has a high output when the input is low, and a low output when the input is high.
What is the relationship between energy input energy output and energy losses whenever transfer of energy takes place?
Energy input = energy output + losses. Both energy output and losses are usually positive (they might also be zero in some specific cases), meaning that (usually) each of them individually is less than the energy input.
What current does the input required to give an output on Lm741?
It depends on the shunt feedback resistor on the op-amp, for example with a 10k feedback resistor connecting the output to the inverting input, 1 mA input current gives 10 volts signal output. The input terminal stays near zero voltage because of the high open-loop gain of the op-amp, so the inverting input is termed a 'virtual earth'.
How does the positive clamper works in electronic circuits?
A negative clamper circuit is considered. It shifts original input signal in a downward direction.While positive input is applied, diode is forward biased. The output voltage is Vo which is equal barrier potential of the diode. The capacitor is charged to V-Vo.When negative input cycle, diode does not conduct because it is reverse biased and the capacitor can not discharge very much because time constant (RC) choosen is high. Now output is sum of input voltage and capacitor voltage and it is equal to -(2V - Vo). Now peak to peak output voltage is difference of output voltages when positive and negative half cycles and it is equal to V-(-(2V - Vo)) or 2V.In negative clamper, input signal is pushed downward and positive peak of the output signal coincides with zero level.In positive clamper circuit, unlike in negative clamper circuit, diode is connected reversely.There is no change in connection of capacitor. But resistor is connected after diode. Positive clamping circuit shifts a input signal in upward direction. The output of this circuit shows that negative peak of signal coincides with zero level.
If the input resistor is 3k ohms and the feedback resistor is 33k ohms in an inverting amplifier what is the voltage gain?
If the input resistor is 3k ohms and the feedback resistor is 33k ohms in an inverting amplifier the voltage gain is -11, the ratio of 33 over 3. Consider this... The negative input terminal is a virtual ground, assuming that the positive terminal is tied to ground (usually) through a resistor. That means you have a simple voltage divider between output and input, and the output will be whatever it takes to get the common point (the negative input) to be zero. From there, its all just Ohm's law.
What is the ideal dc value of output signal when there is no input signal in class b amplifier?
A: If the input is zero the desire output is zero no matter what class it is.
What gate the output will be low for any case when one or more input are zero?
An inverter has a high output when the input is low, and a low output when the input is high.
What is non inverting amplifier?
The amplifier whose output is inphase with it input means if we consider voltage amplification then there is zero phase shift in input and output
What is zero order instruments?
any instrument gives instanteneous result means no time lag in between the input and output, as you give the input you get the output there and then
When will transformer voltage be zero?
A transformer output voltage will be zero when A. The input voltage is zero. B. When the primary (input) wire winding inside the transformer is broken, cut, or burnt out. C. When the secondary (output) wire winding is broken, cut, or burnt out.
Is if the output of the systemis 0 for 0 input it means the system is linear?
No, it does not necessarily mean that the system is linear. A linear system will exhibit a constant scaling property, which means that if the input is multiplied by a constant, the output will also be multiplied by the same constant. It is possible for a system to have an output of zero for a zero input, but still be non-linear if it does not exhibit the scaling property.
What is the DC output if DC input is used in an ac step up transformer?
The DC output will be zero because transformers do not operate on DC there would be a slight peak when switched but then it would settle to zero. Transformers require a changing magnetic field to transfer power.
What is meant by zero phase frequency?
The zero phase frequency is the frequency at which the phase of the input signal and the output signal match.
Can the initial value of a function be zero?
Yes. In general, both the input and the output of a function can be zero.
Full-adder using 4 X 1 multiplexer?
its simple......just you have to make truth table of input and output ......then u will notice that output column can be obtaining by just replacing it by third input or negation of it... in some cases output just hav to connect to one or zero input........for the corresponding output
What is zero drift?
Regarding Instrumentation, is the definition of changes in instrument output when the input signal remains at zero. Caused by factors such as temperature or line voltage.
Is inductor linear or non linear when the initial in it is non zero taking output as current and input as voltage?
Linear
