Xc(capacitive reactance) = 1/(2piFC)
XL(inductive reactance) = 2piFL
Where pi=3.14etc.,
F=frequency and C and L are capacitance and inductance.
Please pardon lack of proper symbology.
Inductive reactance, XL=2piifl, where f is frequency and l is the inductance.
Capacitive reactance, XC=1/2piifc, where f is frequency and c is the capacitance.
The operator, 'j', is used to indicate a phasor quantity that has been rotated, counterclockwise, through an angle of 90 degrees.So, if (for example) the operator is applied to a voltage U, then it is written as jU, which indicates means that the voltage lies along the vertical positive axis. A further operation by j, results in jjU, or j2 U, which means that the voltage lies along the horizontal negative axis -so, j2 is equivalent to -1U (or j is equivalent to the square-root of -1) or, simply, -U.A further operation by j, results in the voltage lying along the negative vertical axis: that is: jjjU = jj2U=-jU.But to answer your question, for inductive reactance (XL), we express impedance (Z) a follows: Z = R+jXL and, for capacitive reactance (XC), we express impedance as Z = R - jXC (the L and C should be subscripts).Strictly-speaking the operator j doesn't actually apply to impedance, because impedance, resistance, and reactance or not phasor (vector) quantities. So if we wanted to be strictly accurate, the above equations should be written as:(E/I) = (UR/I) + j (UL/I) and (E/I) = (UR/I)- j (UC/I)...but this is being rather pedantic.
Resistors in A.C circuits completely, absolutely and totally follow ohms law. Ohm's law is followed by resistances and has nothing to with the alternating or direct nature of current. Ohm's law is however not followed by non linear loads. Also, in A.C systems we generally write V=I*Z which is analogous to V=I*R in D.C circuits. For capacitive and inductive circuits the current magnitude varies in accordance with the circuit impedance but there is a phase shift corresponding to the lagging/ leading nature of current. Conclusion: it's absolutely wrong to say that ohm's law is not followed in A.C. Its as much applicable to AC systems as to DC systems.
The balanced equation for the reaction involved is as follows: C10H12O2 + Br2 + H2O ---> C10H13O3Br + HBr. Some C10H12O2Br2 will form as well.
Reactance of capacitor is inversely proportional to frequency. I should not need to write the exact equation here, its in your textbook. All you need is that its inversely proportional to frequency for proof.We will now assume an ideal capacitor to keep the analysis simple.at DC the frequency is zero, the inverse of this is infinite reactance: open circuitat low frequency AC frequency is low, the inverse of this is high reactanceat midrange frequency AC frequency is midrange, the inverse of this is midrange reactanceat high frequency AC frequency is high, the inverse of this is low reactanceat infinite frequency AC frequency is infinite, the inverse of this is zero reactance: short circuitThis disproves your original statement as written, except for the special cases of DC and infinite frequency AC (which does not occur), for ideal capacitors.As all real capacitors are nonideal, they have leakage resistance. This means that even for the special case of DC the capacitor is not a true open circuit, just a very high resistance resistor. Which also disproves it for the remaining case of DC in real capacitors.
A c program is also known as a computer program. A singular matrix has no inverse. An equation to determine this would be a/c=f. <<>> The determinant of a singular matix is zero.
You can write this as a complex number; the resistance is the real part, the reactance is the imaginary part (negative, for a capacitive reactance): 15 + j10 kilohms. ("j" is used instead of "i", to avoid confusion with current, which is symbolized by "i".) This is in rectangular coordinates; with a scientific calculator you can use rectangular --> polar conversion, to get the absolute value and the angle. To get just the absolute value, use Pythagoras' Theorem, which in this case gives about 18 kilohms.You can write this as a complex number; the resistance is the real part, the reactance is the imaginary part (negative, for a capacitive reactance): 15 + j10 kilohms.

Write an equation of 3/8×112
Yes, you can write an equation out in words. This is often done to make clear what the equation in numerals is.
