Physics

An ac generator has a frequency of 7.5 kHz and a voltage of 35V. When an inductor is connected between the terminals of thisgenerator, the current in the inductor is 30 mA. What is theinductance of the inductor?

Frequency of ac generator (f) = 7.5×103 HZ

Voltage (E) =35V

Current in Inductor (I) =30 × 10-3 A

Inductance of the Inductor (L) = E/IW

                                                      = E/I (2πf)

                                                      = 35/(2 × 3.14 × 7.5 × 103 × 30×10-3)

                                                      =2.47 × 10-2 Henry
