Hello! I need a little bit of help for my homework
Here is the problem
An impedance oil takes 144 watts at a lagging factor of 0.6. What values of capacitance and resistance should be connected in series with the coil if the power input to the latter is to remain unchanged and the overall circuit is to be unity? Voltage is 60 v and frequency is 60Hz.
I keep on getting 60Ω for the resistance and 66.31x10μf for the capacitance which are hugely different from the correct answers which are 55.3μf for the capacitance and 24Ω for the resistance.
I need help with the formulas because I am in no doubt that I am using incorrect formulas. I've searched, googled and tried to use lots of them but still I am not able to get the correct answers, I've been trying to solve this for 3 hours now and I am really getting frustrated.
Please lighten my burden. Thank you.
