If you increase or decrease the frequency what effect on electrical machin?

If you're talking about an electric motor, increasing the frequency will increase the speed of rotation of the motor, and decreasing the frequency will decrease the speed of rotation of the motor.
The other way of controlling a motor is to control the current; increasing the current increases speed, decreasing current decreases speed.

How does doubling the frequency effect the reactance of an inducter and capacitor?
for inductor, reactance XL = 2*pi* f *L, if frequency doubles then reactance increase. But for capacitor, reactance Xc = 1/(2*pi*f*C). In this case if frequency doubles the reactance decrease.
What are the three factors that effect the electrical parameters of a op-amp?
Supply voltage , temperature , frequency are factors that effect the electrical parameters of opamp
The decrease in effective conductor cross section at high frequencies?
Is called skin effect. The higher the frequency, the worse the issue.
What effect does increasing the timing capacitor have on the frequency out of an Astable 555 timer?
frequency drops
What causes resistance to increase or decrease?
Voltage, if voltage is increased resistance in the circuit increasesAnswerResistance is determined by the length, cross-sectional area, and resistivity of a conductor. Resistivity is, in turn, affected by temperature -so temperature indirectly affects resistance.These are the only factors that affect resistance. Voltage and current have no direct effect whatsoever on resistance. Current can affect resistance indirectly if it causes the conductor's temperature to increase.For AC circuits, 'skin effect', due to frequency, causes the current to flow towards the surface of a conductor which acts to reduce the effective cross-sectional area of that conductor. So, frequency can also indirectly affect resistance.
Does the Doppler effect increase wavelength and decrease frequency?
Yes
What is the effect of low frequency on the voltage?
The frequency would decrease the gain and increase the output voltage
What effect if load increase in electrical system?
when load on the electric system increase frequency of the system will decrease resulting in higher intake at powergenerators. If higher intake is not net by powergeneration stations entire power system will collapse. It is called grid failure.Another AnswerAn increase in load will result in an increase in load current.
What does a blue and red shift of absorption lines in a spectrum indicate?
Blue shift is a decrease of a signal's wavelength, and/or an increase in its frequency, due to the Doppler Effect. This indicates that the object is moving towards the observer.Red shift is the increase of a signal's wavelength, and/or a decrease in its frequency, due to the Doppler Effect. This indicates that the object is moving away from the observer.
Is redshift and Doppler effect the same?
No, but they are closely related. Doppler effect is a change of frequency related to relative movement of source and observer. Depending on the relative movement, the perceived frequency may increase or decrease. The term redshift is used specifically in the case of electromagnetic waves (such as light), and specifically if the source and the observer are moving away from each other. In this case, the frequency of the light will decrease.
Does frequency affect wave speed?
The speed of a wave doesn't depend on its frequency.REASON:According to the formulaV=frequency * Lambdaso,V/ Lambda= frequencyHere,Frequency is inversely proportional to the wavelength. so, If we increase the value of frequency then by same amount frequency will decrease and will cancel out the effect of each other the "V" will remain constant.
How bronchial asthma effect on lung volume and capacity increase or decrease and why?
decrease -
What is the output effect and the price effect for an oligopoly?
Since P>MC for an oligopoly, the output effect is that selling one more unit at the sales price will increase profit.The price effect is that an increase in production will increase the total amount sold, which will decrease the price and decrease the profit on all other units sold.If the output effect is greater than the price effect, the owner will increase production.If the price effect is greater than the output effect, the owner will not increase production (and may even decrease production).Oligopolists will continue to increase or decrease production until these marginal effects balance.
What is the effect of an increase in consumer income on demand for a good?
They both will increase (or decrease).

What phenomenon is the basis of police radar and makes light or sound waves increase in frequency if the source is moving toward the observer and decrease if the source is moving away?
Its called the doppler effect.
