Question

I'm in electricity and magnetism physics. I am having trouble understanding this problem. Can you please explain each step. And show how to check this problem. Thank you
ticular inductor has appreciable resistance inductor has appreciable resistance. When the inductor is connected to a Variation of 21.74: A par 12-V battery, the maximum current in the inductor is estance. W with 12Vrms, the current drops to 2.0A a) What are i) the impedance at 60Hz, and ii) the in the inductor is 3.0 A. When it is connected to an AC 60-Hz source OHz, and ii) the inductance of the inductor? We sweep the source and measure the How much stray capacitance is in this inucor? cep th souucitance is in this inductor? Ht:Assume that we have a series RLC circuit ure the current through the inductor and it has a maximum at 1.0 MHz b)

Explanation / Answer

(A) Imax = V / R

R = 12 / 3 = 4 ohm

(i) impedance = 12 / 2 = 6 ohm

(ii) Z = sqrt(R^2 + XL^2)

6^2 = 4^2 + XL^2

XL = 4.47 ohm

and XL = 2 pi f L

L = 4.47 / (2 x pi x 60) = 0.0119 H Or 11.9 mH

(b) for maximum current,

XL = Xc

2 pi x 10^6 x 0.0199 = 1 / (2 x pi x 10^6 x C)

C = 2.135 x 10^-12 F ......Ans
