I've indicated The direction of current in second figure(Is it correct?). The current is due to charged capacitor(you can see the charge on the capacitor is Q). So what voltage equation would you write?
The Voltage polarity across the inductor is same as that across the capacitor since both are in parallel and the voltage across them must be same.
But when Inductor, capacitor and resistor are connected as shown in the second figure what would be the voltage polarity across the inductor and...
I can't figure out what actually is the Pich-off voltage of a JFET.
I basically have confusion between these two definitions:
Pinch off voltage is that gate source voltage at which there is no drain-source current
Pinch of voltage is that 'Drain-Source' voltage after which the drain source...
Homework Statement
lim (x,y)\rightarrow(0,0) f(x,y)=2*x/(x^{2} + x +y^{2})
Homework Equations
used different paths like y=k*x ,where k is a constant and y=k*x^2
The Attempt at a Solution
Got an answer 2 but solution says does not exist. Can anybody convince me that why limit does...
Is it possible to claculate ∫[cot(x)]dx from x=0 to x=\piwhere [.] represents floor functon or the greatest integer function??
it seems impossible to me but can we use the properties of definite integrals to somehow evaluate the area?
Potential energy is the work done in bringing a unit mass from infinity to the center of sphere.
U=integral[from infinty to zero](F.dr.cos(x)) here x=0=>cosx=1.
now f is not constant. it is different outside the sphere and also inside(non uniform density).
Break the integral for outside the...
I think you're saying that we first charge a capacitor ' A' with battery 'B'. then we wait 5 secs for the capacitor to get charged and then we throw the battery 'B' and place another capacitor 'C' in its(B's) place,with our insulating gloves.
I think the charge would be conserved and potential...

i've just learnt de broglie wave equation in chemistry which tells that matter can act as wave.
if an electron is moving at a certain speed(v) at which its wavelength is comparably in meters. If a football is made to move at the same speed (v),will it behave as a wave? Since Football also has...
What is a photon?
Does it have mass?(if no then why it has momentum)
it travels with speed of light?
Has it some wavelength associated with it,that can be calculated by De Broglie wave equation?
Two straight current carrying conductors A and B are lying in a vertical plane as shown.The separation between them is h and mass per unit lenght of wires is λ.Keeping one wire fixed (say A),Bis raised by small hieght δh.
