What is stronger higher amps or watts in a electric motor?
Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. You can relate the two if you know the Voltage. For example, if your car has a 12V battery and your stereo draws 10 Amps of current, you are using 120 Watts of power. [Power in Watts] = [Voltage in Volts] x [Current in Amps]
When describing waves what does amplitude refer to?
The amplitude is the maximum amount it sways from the neutral position. If it oscillates about zero, then it would vary from a value of +A to -A, where A is the maximum Amplitude. The units of A will be determined by the type of wave.
What is regular periodic waveforms?
Frequency: Frequency is also equal to the wavelength divided by the velocity and is designated as the number of cycles (or peaks) per second. Amplitude: Amplitude is the absolute value of the magnitude of the displacement of a wave from a mean value and is designated as mV
What is the highest amplitude on a seismograph?
surface waves
Why value of hall coefficient is negative?
The Hall coefficient has the same sign as the charge carrier. The charge carrier in a normal electric current, the electron, is negative, and as a result the Hall coefficient is negative.
Maximum value of voltage or current?
Amplitude
What is maximum current?
If you are referring to an a.c. current, then the maximum current is the amplitude of its waveform. For a sinusoidal waveform, the amplitude of an a.c. current is its root-mean-square value, divided by 0.707. For example, an a.c current with an rms value of, say, 10 A will have an amplitude of 14.14 A,
The RMS value of potential difference or current for a sine wave is always times how many times the amplitude.?
The RMS value in this case is the amplitude divided by the square root of 2. Approximately 0.7 times the amplitude.
What is difference between amplitude and peak value?
It is the highest value of the amplitude, called the peak value. Scroll down to related links and look at "RMS voltage, peak voltage and peak-to-peak voltage". Look at the figure in the middle below the headline "RMS voltage, peak voltage and peak-to-peak voltage".
The instantaneous value of current in an AC circuit is represented by 150 sin 2π x 30t What are the amplitude and frequency of the AC wave?
The amplitude is 150; 30
What is the difference between wavelenghtand amplitude?
The wavelength is the distance the wave travels before repeating in meters. The amplitude of the wave is the deflection from peak to trough in units of the wave value, e.g electric field or velocity.
What is voltage amplitude?
Voltage amplitude is the maximum value of a voltage.

Current market value
Why the current flowing in secondary coil in mutual induction momentry?
In a transformer the AC is producing and expanding and collapsing magnetic field where the amplitude and direction of the current changes constantly and based nominally on a sine wave. Therefore, at any instant of time that you measure the current at a point, it is different. So the current is continuous and not momentary, but your measurement only has a fixed value at the time of the measurement. An infinitesimal time later, the value and perhaps the direction would be different.
How do you measure and wavelength?
The wavelength is the distance from one peak (or trough) of the wave to the next peak (or trough). The amplitude is the distance from the mean value to the top of the peak (or the bottom of the trough). Alternatively, the amplitude is one half of the distance between the height of peak to the depth of the trough.How you measure these depends on the nature of the waves.
Does R value means the resistance a material has to the flow of heat?
No, to the flow of electric current.
How do you measure current without connecting the load?
Without load there is no current so it is impossible to measure it.
