The maximum value is when the imaginary part is 0. Z = V / I = 150 / 9,97(real part) = 15A

Xl = sqrt(25^2 - 9,97^2) Xl = 22,93 w' = 1528,67 and f' = 243,3 (23,6% reduction) Thanks How I find maximum possible value for the current ?

We determined the constants R and L of a coil by placing it in series with a standard resistor of 10 ohms and reading the voltages on the terminals of Rs, the coil and the series circuit complete. What are the values of R and L for the following voltage readings at 60 Hz: Vrs = 20; Vcoil =...

To find w' I need z'. How calculate z' ?

Impedance -- Current phasor In a series circuit of two elements, the voltage and current, for w = 2000 rad/s, are V = 150|-45° and I = 4,74|-116,6°.That variation in the frequency of the source would result in a phasor current of 6 amps? Assuming an unlimited variation in the frequency, what is...

Yes I find Q = -q is correct ?

This is my doubt

A charge Q at a vertex of a square and another Q on the opposite corner of the square and other two charges q each of the other vertices. If the force eletrogmanetica on Q is null which the value of Q in terms of q? There is a q such that the resultant force on 4 charges is zero? My attemp...

Thank you

Find a general formula for the temperature u(x,t) in the form of a series with general formula for the coefficients of the series. \alpha^2 \frac{\partial^2 u}{\partial x^2} = \frac{\partial u}{\partial t} with 0 < x < L; t>0 u(0,t) = 0 \frac{\partial u}{\partial x} (L,t) = 0 with t>0...

I find the equation of beat: x(t) = [\frac{2F_o}{m(w_o^2 - w^2)}sin(\frac{(w_o - w)t}{2})]sin(\frac{(w_o + w)t}{2}) What values do I get to F_o, w_o and w to generate the graph ? I use program maple to plot graph.

Thank you

The equation and solution I found. I wonder what is resonance and what are its effects

Thank you

Thanks
