Multiplechoice questions may continue on the next column or page – find all choices before answering. The due time is Central time. Covers 31.131.6 Changing the Frequency 33:04, trigonometry, numeric, > 1 min, nor mal. 001 When a particular inductor is connected to a sinusoidal voltage with a 120 V amplitude, a peak current of 3 A appears in the inductor. What is the maximum current if the fre quency of the applied voltage is doubled? An swer in units of A. 002 What is the inductive reactance at the new frequency? Answer in units of Ω . Inductive Circuit 33:04, trigonometry, numeric, > 1 min, nor mal. 003 In the purely inductive circuit in the figure below, the inductance is 25 mH and the rms voltage is 150 V. E = E max sin ω t E rms = 150 V S 25 mH Find the inductive reactance if the fre quency is 60 Hz. Answer in units of Ω ....
