The resonance frequency of 1200 What is the resonance frequency if the inductance L is doubled?
1200/sqrt(2) = 848.5 (rounded)
How will the resonance frequency change If the resistance in an RLC circuit is doubled but he capacitance and inductance are unchanged?
For to keep the resonant frequancy constant L*C has to stay same. Lets say if you double L you have to divide C by 2 to keep the same resonant frequency. If only L increases Resonant frequency decrease, this is same for C.
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What happens to the capacitive reactance when the frequency is doubled?
DATE: 17-MAY-12 THE CAPACITIVE REACTANCE VARIES INVERSELY WITH THE AMOUNT OF THE PRODUCT OF MAGNITUDE OF THE SUPPLY FREQUENCY, TWICE THE VALUE OF CONSTANT PI AND THE MAGNITUDE OF CAPACITANCE. IN OTHER WORDS, EVERY TIME YOU INCREASE ANY OF THESE FACTORS OR IF SAY YOU FIX THE VALUE OF CAPACITANCE TO SAY 1 MICROFARAD AND OTHER FACTOR (i.e. 2 x PI) AS CONSTANT ALSO, BUT THEN WHEN DOUBLING THE FREQUENCY, SO THEN THE EFFECT TO THE CAPACITIVE REACTANCE WILL BE INVERSELY OR HALVED. THE MORE YOU INCREASE THE FREQUENCY, THE SMALLER THIS VALUE WILL BE. WHICH IN EFFECT ALLOWING MORE HIGH FREQUENCY CURRENT OR VOLTAGE TO PASS THRU THE CIRCUIT. AND THE REVERSE IS TRUE, MEANING ONCE YOU ALLOW LOW FREQUENCY CURRENT, THEN THE CAPAICTIVE REACTANCE WILL INCREASE AS A RESULT. BY FMSJr. / ABU DHABI, UAE
What happen to current in a circuit if the voltage is not charge but the resistance is doubled?
The current in the circuit will be decreased by half. Ohm's law states V=IR so, I=V/R. If R is doubled, then I= V/2R.
When modulating freq is doubled then modulating index is halved and modulating voltage remains constant system is?
It's Angle modulated system where the amplitude remains constant & frequency & phase varies with respect to modulating signal.
If a wave is moving at a constant speed and the wavelength is doubled what will happen to the frequency?
IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).
If the frequency of a wave traveling in a rope is doubled what will happen to the speed of the wave?
Assuming that the wavelength remains constant, the velocity of the rope will also double if the frequency is doubled. This can be seen in the word equation below: speed = frequency x wavelength If we assume that wavelength is a constant...let wavelength = 1 speed = frequency therefore... 2 x frequency = 2 x speed
If the frequency is doubled then for waves what would be the wavelength and vlocity?
Frequency = Velocity divided by wavelength. So if frequency is doubled that means velocity is doubled but the wavelength is halved. You can see this by keeping wavelength a constant : If Frequency =1 and Wavelength= 1 1= Velocity/1 Velocity=1 If Frequency =2 and Wavelength= 1 2= Velocity/1 Velocity =2 OR keeping Velocity constant: If Frequency =1 and Velocity= 1 1= 1/Wavelength Wavelength =1 If Frequency =2 and Velocity= 1 2= 1/Wavelength Wavelength=1/2
How does the frequency of a wave change when the period of a wave is doubled?
The frequency is the reciprocal of the period. If the period is doubled, the frequency will change by a factor of 1/2.
What happens to the wavelength of a wave when the frequency of the wave is doubled?
the wavelength of the wave get smaller, decreases because the frequency is doubled, increasing..vise versa.
Is the stopping voltage doubled or more than doubled if frequency of lightwave is doubled under the condition where intensity is constant?
More than doubled. The stopping voltage is the photon energy minus the work function: hv - W Doubling the photon energy creates a new stopping voltage of: 2 hv - W > 2 (hv - W)
What happens to the resistance when the frequency is doubled?
Impedance of a coil or a capacitor does depend on the excitation frequency,but resistance has no relationship to frequency.
What happens to the wavelength if the frequency is doubled?
If the frequency is doubled then the wave length and period will be halved because in the same time that the original wave occurred, you will now see 2 waves. .here is NO change in its its speed.
What happens to an electromagnetic wave the frequency is doubled?
The speed halves.
What happens to an electromagnetic wave when the frequency is doubled?

What happens to an electromagnetic wave when frequency is doubled?
