Does the formula tan (phi) = (wL - 1/wC)/R work without a capacitor? Can I turn it into tan (phi) = wL/R instead? I don't know what formula to use to find the inductance of an inductor in this question:(adsbygoogle = window.adsbygoogle || []).push({});

A voltage source V = 160V sin (100t) is connected in series with an inductor and a 17.0 ohm resistor. The phase angle between the current and the voltage is 1.05 rad. Find:

a) the inductance of the coil, and

b) the average power consumption of a circuit.
