In a certain RLC circuit, the rms current is 6.72A, the rms voltage is 230V, and the current leads the voltage by 55.9 Degrees.(adsbygoogle = window.adsbygoogle || []).push({});

a)what is the resistance of the circuit?

b)calculate the total XL-Xc

c)Calc. the average power dissipated in the circuit.

a) 1.92E1 Ohms

b)?????

c)8.665E2 J

I can't figure out b! I tried using

tan x = X/R

tan 55.9 = (Xl-Xc)/(1.92E1 Ohm)

But this did not give me the right answer...maybe i am just doing the math wrong here....would you do this to solve for (XL-Xc)?

(1.92E1 Ohm)tan 55.9 = "x" ?

Thanks
