[SOLVED] need to understand very simple circuit diagram

[mitultaillor]

i want to understand very simple circuit as I am confused.
In file name pic1 attached with this question, What voltage should be there across capacitor? I think it is going to same as its parallel to voltage source. what do you think?
In file name pic2 attached with this question, what is effect on voltage across capacitor if we increase frequency?? I have no clue for that answer.

I would really appreciate if any one can explain me in detail.
thank you very much for your time. I really appreciate it.

Indeed, it's very simple. And therefore, I am not sure if it is really helpful for you to read the answer here in this forum.
Such simple questions are treated in detail in every textbook on electronic basics.
In your own interests - that is my recommendation.

LvW,

thank you for your answer. I am confused and hence I have posted this question to know in detail. I would appreciate if you would tell me.

many thanks

1. Charging a capacitor:
Capacitor Discharging
So after a short period of time Vcapacitor= U =10V
2. Capacitor reactance

Capacitive Reactance
Capacitive Reactance
:smile:

Oscillator frequency -> very high > Capacitor reactance => 0 > voltage on capacitor = 0
Oscillator frequency > low > Capacitor reactance > high > voltage on capacitor > high
DC > voltage on capacitor = U power supply
