# Complex Number RLC Series Parallel Voltage and Current Supply

Hi Everyone.

I have been looking at this questions for a while now and have just hit a brick wall.

I have found the source impedances using the the following

Z of Current source = 1KΩ - jXC

=1000 - j4000Ω = 4123<-75.96°

Z of Voltage source = 4KΩ + jXL

= 4000 + j1000Ω = 4123<14.04°

Correct ?

But from here I am not sure how to approach determining the current I2.

Any kind of guidance would be greatly appreciated.

Thanks

how did you got your value for Xc ?

Plus ! you can use KVL in the loop having voltage source !

Using the following formula:

1/jwC

=1/j(25K rads/sec)(10nF)

Thanks

shouldn't the angular frequency should be converted into hz ?

I could'nt be sure but I assumse that when the formula states Omega it uses its standard form.

i think we need to convert it !
