Hi all, I would really appreciate some guidance on the following question. Unfortunately my Tutor contact isnt great at distance learning so any help would be great.

Question: Demonstrate how to calculate impedance in an rlc cicuit containing 300mH Inductor, a 300MicroF capacitor, a 2.7MΩ resistor at 100Khz frequency.

My attempt:

XL = 188400

XC= 0.005

188400-0.005 = 188399.995

188399.995 * 188399.995 = 35494558116.0003

R= 27000000*27000000 = 729000000000000

729000000000000+35494558116.0003 = 35521558116.00003

The square root = 270006573.0580611Ω

I hope thats correct and as said any help with the structuring is much appreciated

Use scientific notation to 4 significant figures.
Show the formulas for XL and XC.
