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

Solutions

Expert Solution

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
