Como no dipolo R é da ordem de 73 ohms e na Magloop R é menor que 1 ohm, a grande diferença entre as duas antenas é o fator Q=2PiFL/R, que será bem mais alto na Magloop do que no dipolo. It is connected to a standard wall socket (120 V rms, 60. The more frequency will cause max voltage to reach min faster, and min current to reach max current due to the way that capacitors gather and store voltage while inductors block current, forcing it to work it's way through the spiral wire. X L = 2piFL = 2*3. The formulas for reactance (a measure of resistance to AC voltage) are, for capacitance: Xc=1/2piFC and Xl=2PiFL. Tweak the inductance value till you get close to the desired reactance value of 1929. I feel it is important to differentiate between phase shifts which are a result of relations between "proper" reactive components, and shifts which relate specifically to the fixed (offset) structures which have a mutually inductive and or capacitive relationship within the system.

Regard the source voltage as having zero phase. Search the world's largest database of electronic test equipment. I am not 100% what you are after, but if it's this Inductive Reactance XL=2pifl (2 x pi x frequency x inductance) Capacitive Reactance XC= 1/2pifc (1 divided by 2 x pi x frequency x capacitance) Total Impedance Z= Square Root of R2 + XL2 or XC2 For Combined circuits Z=Square Root of R2 + (XL-XC)2 Enter the largest value first of (XL-XC). Assuming that you eventually get a measurement of the current and voltage applied, use Ohm's law and Xl=2PifL to calculate the inductance. This is the electronics and communication engineering questions and answers with discussion section on "Measurements and Instrumentation" with explanation for various interview, competitive examination and entrance test. Just enter the value of the radius and hit calculate button. 58 degrees Following assumptions were made : 1.
