How come low frequency current needs a return path but high frequency current does not?
The higher the frequency the lower the impedance is in air, vacuum or other insulation. High frequency usually finds its return path via stray capacitance. Some part of the energy is radiated by the conductors, as they form an antenna, even if not intended to do so. In this case the antenna impedance provides the return path.
What else can I help you with?
Is frequency directly inversely equal or have no bearing on wavelength?
Frequency and wavelength are inversely related in a vacuum, meaning as one increases, the other decreases. This relationship is described by the equation: wavelength = speed of light / frequency. In a medium, the relationship can be more complex and factors such as refractive index come into play.
What must change when a sound gets higher?
When a sound gets higher in pitch, the frequency of the sound wave increases. This means that the vibrations of the sound wave occur at a faster rate. The higher frequency results in a perception of higher pitch by our ears.
From where do the moving electrons in an electromagnet come?
The moving electrons in an electromagnet come from the flow of electric current through a wire or coil.
What happens if two sound waves having the same frequency interfere in phase?
If two sound waves with the same frequency interfere in phase, they will reinforce each other, resulting in constructive interference. This will create a louder sound.
What is short frequency?
Well, I assume you are talking about waves, am I correct? Frequency is the distance between the crest and the trough of a wave. Gamma rays are the waves of highest frequency that we know of. Ultraviolet possesses a frequency just above the frequency of visible light (remember ROYGBIV). Descend in frequency beneath red and you'll come to infrared. While snakes can detect this (I am not yet sure how) the human eye cannot detect anything of this low frequency although we often use this in modern technology (note nightvision goggles). The higher the frequency, the smaller the wavelength and vice versa. Radio waves have an extremely short frequency and an extremely long wavelength.
Bandwidth vs frequency?
Bandwidth is the amount of information that can come through. The frequency is how quickly the information can come through.
Does return mean come before?
Return means to come back again.

How come some animals return home and others don't?
Instinct is the short answer. It isn't necessary for all animals to migrate. It depends on how they are made and what their needs are.
What changes in the when you increase the wavelength?
The frequency becomes lower. Frequency is how fast the waves come by.
What changes in the wave when you increase the wavelength?
The frequency becomes lower. Frequency is how fast the waves come by.
Why won't the old guy get off his computer on counterfeit island?
He needs to be distracted, so you can return his Tour tickets to him. Go to the Clown Store and get a green balloon, and give it to the kid in the Country Side. When you come back, you can return the tickets.
What is the confirmation that you will come back return after the complication of?
The confirmation that you will come back or return after the complication is called assurance.
What is return in french?
Retour. Return as in 'go back' is Retourner. Return as in 'come back' is Revenir.
What is the frequency of a grasshopper?
They have a low frequency. Grasshoppers can also alter their sound to stay in tune to specific noises they come in contact with.
What is the definition of return?
To come back
