RL Circuit EXERCISE 4

Exercise4


1.         Suppose a coil has an inductance of 0.500 H, and the frequency of the ac passing through it is 60.0Hz. What is the inductive reactance?


2.         What will be the inductive reactance of a coil (inductance of 0.500 H) if the supply is a battery that supplies pure dc?


3.         If a coil has an inductive reactance of 100 ohms at a frequency of 5.00 MHz, what is its inductance?


4.         Suppose an RL circuit operates at a frequency of 1.0 MHz with a resistance of 10 ohms and an inductance of 90 mH. What is the phase angle?


5.         Suppose the inductive reactance in an RL circuit is 680 ohms and the resistance is 840 ohms. What is the phase angle?
