The ub with 2 arrows is the start of the circuit, and J=I2= 1A.

Ok, I'm sorry. After writing there I don't know how to continue to find any I, and also I don't know how to calculate Uef.

Hello, i have this circuit as a homework. And i have to find all the I's, and Uef, i got stuck at writing Kirchhoff's laws in this circuit, do you think you can help me write them, and also can you explain how can i calculate Uef?

After solving this is what i got. I know i should calculate v2 max value so where i wrote sin(2pi*10000t) i thought that the max value of any sin is 1 so that means the fraction will be 1/(2*pi*10000). Did i solve this any good?

I took v1 as coswt where w is the 2*pi*frequency ( in this case the teacher said to pick the frequency 10000). Is this correct as a formula for v1 or not?

The value of V2. Sorry!

Hello, i am student from Romania ( first year) and my physics teacher told us to solve this problem. We know that C=150 nanofarad, R= 1000 ohms, and the frequency we should take is more then 1061 ( 10kHz, to be more exactly). My problem is that i don't know what to take as V1 ( i took it coswt...
