I'm an old dog, trying to learn new tricks, and I'm just not getting it.
I did good in the DC Circuits class, but I'm struggling in AC.
Our professor gave us some look alike questions to help us study for an upcoming test. I wrote so quickly, I can't make out my notes very well.
Please take a look and see if you can point me in the right direction.
Let me know if my notes make sense...
Thanks,
Gary
1. Amplitude Pk @ 400Mv AC
A. Volts AC / .707?
2. P-P A of 700 mV RMS 1.98 V
A. RMS/.707 = P x 2 = P-P?
3. RMS 345 mV AC
A. RMS/.707?
4. Pk 100 mV
A. 100 mV/.7.0?
5. Avg 10V/.707x.637= 9.01V
6. P-P .900V
A. .9/.707 =x2 = 2.55v
7. e-inst =sin x pk
8. 45 deg elec points... sin RMS voltage?
9. 135 deg elec points .707
10. e-inst @45 deg diff - slope
elec % pt at 135 deg
11. 45 deg & 225% diff
12. 40 Pk sin 24 V e inst
13. T of 1 cycle 466 mA
14. 350NS 2.86M 6?
15. F=300 K Hz =3.33 micro S?
16. 666 cyles in 1 Sin in 1 Second 1.5M minus 1.5 micro?
There are a lot more, but they are similar to these.
If I can solve these, I should be able to solve the others as well.
