O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
8.14 PROBLEMS
- Find the equivalent impedance and admittance at ω = 100π rad/s for the circuits in Fig. 8.14-1.
Fig. 8.14-1
- A resistor of 200 Ω and an inductor of 0.5 H are in series. (i) Find the impedance of the combination at 60 Hz in rectangular form and polar form. (ii) Find a parallel RL circuit that has the same impedance at the same frequency. (iii) Find the impedance of the parallel equivalent in step (ii) for 50 Hz. Are the impedance values equal for the two circuits at 50 Hz?
- A resistor of 200 Ω and a capacitor of 0.05 mF are in parallel. (i) Find the impedance of the combination at 60 Hz in rectangular form and polar form. (ii) ...
