Calculate

a) circuit impedance- answer z=8+j10.48 xL=50.27 xc=39.79

b) current flowing- answer- 15.17 with angle -52.64

c)voltage across coil answer 762.6 with angle 37.36

d) volts across capacitor answer 603.61 with angle -142.64

those answers are correct according to my tutor the next question is where i am stuck

**What additional impedance would need to be added to the circuit for resonance to occur?**now i know XC must equal XL and that there is a formula for resonant frequancy and q-factor etc however i am usure of this extra impedance it is asking for. the questions are then thge same as above but to find out the new values.

any help to find the impedance needed would be a great help as i only attend college one a week as part of work so i am unable to seek help from teachers once at home and this is referall work.

thanks in advance
