Code39 Maker In None Using Barcode drawer for Software Control to generate, create Code39 image in Software applications. significant figures, is 89 . The circuit contains an almost pure inductive reactance, because the phase angle is close to 90 . The resistance contributes little to the behavior of this RL circuit at 1.0 MHz.

Painting Code 39 In Visual C# Using Barcode encoder for .NET framework Control to generate, create Code39 image in .NET framework applications. Problem 136 What is the phase angle for the preceding circuit at a frequency of 10 kHz With that information, what can we say about the behavior of the circuit at 10 kHz This requires that XL be calculated again, for the new frequency. Let s use megahertz, so it goes in the formula with microhenrys. A frequency of 10 kHz is the same as 0.010 MHz. Calculating, we get XL = 6.28fL = 6.28 0.010 90 = 5.65 . The ratio XL/R is 5.65/10 = 0.565. Therefore, the phase angle is arctan 0.565, which, rounded to two significant figures, is 29 . This is not close to either 0 or 90 . Thus, at 10 kHz, the resistance and the inductive reactance both play significant roles in the behavior of the circuit.
