What frequency is inductive reactance equal to resistance

Reference no: EM13538053

A coil has resistance R=14Ohms and inductance L=3milliHenries and is powered by a generator with variable frequency and maximum voltage V = 10Volts.

(a) At what frequency is the inductive reactance equal to resistance? This is when Z=sqrt(2)*R.

(b) What is the average power used by the coil when the generator operates at the frequency you found in (a)?

(c) What is the average power used by the coil when the generator operates at 60Hz?

(d) What is the average power used by the coil when the generator operates at one-thousand times the frequency in (a)?

(e) What is the average power used by the coil when the generator operates at one-thousandth of the frequency in (a)?
