I have been given a quesiton asking me to calulate the following parameters and write the answers in polar form (i) Z, (ii) I(subscript)T (iii) V(subscript)R, (iv) V(subscript)C given that V1=2sin(2pi1000t). The circuit diagram consists of a series circuit containing R1(1kOhms) and C1(1nF), I mostly understand how to calculate Z and Vr however do not understand how to calcute I(t) or V(c), is I(t) the same as calculating just I? There is also a parralell circuit question which i am stuck on where the circuit contains C2(10uF) and R2(22kOhms) in parrallel with the same V1=2sin(2pi1000t)

One question at a time, otherwise chaos ensues.

Provide a schematic and show YOUR best attempt to work the problem. That way we can see what you are getting right and were you are going wrong.

hi eddy,
What do you calculate the V1 frequency value?

value is V1=2sin(2pi1000t)

hi,
So what is V1 over a 1sec period, in Hz

i believe its v1 = 2 sin(pi(1000Hz)t)

sorry...
