An rl circuit consists of a 44.0 ω resistor and a 2.20 mh inductor. find its impedance z at 60.0 hz and 10.0 khz. (enter your answers in ohms to at least four significant figures.)

44 ohm, 145 ohm

Explanation:

R = 44 ohm, L = 2.2 mH = 2.2 x 10^-3 H

At f = 60 Hz

XL = 2 π f L = 2 x 3.14 x 60 x 2.2 x 10^-3 = 0.82896 ohm

Impedance,  

Z = 44 ohm

At f = 10 kHz = 10000 Hz

XL = 2 π f L = 2 x 3.14 x 10000 x 2.2 x 10^-3 = 138.16 ohm

Impedance,  

Z =1 45 ohm
