# RLC AC Circuit f and ω

## Homework Statement

I am given a RLC circuit with a AC power source (e.g. signal generator), and i want to find the reactance of the capacitor.

Given: R = 2200 Ohms, L = .025 H, C = (1 x 10-9) F, V0 = 5 V
f = 3000 Hz

## Homework Equations

edit: Sorry i wrote wrong formula.. here is the correct one:

Reactance of Capacitor = 1 / ω C

## The Attempt at a Solution

I know how to solve this problem, but i am not sure what value to use for ω.

My teacher refers to ω as the "frequency", but isn't it supposed to be ω = 2 pi f ?

So, simply put, am i supposed to use the 3000 Hz as my ω, or do i use 2 pi f as my ω?

Use ω = 2 π f. Also there is no V0 in the reactance.

i learned that ω is the angular frequency.. so am i supposed to use ω = 2 pi f for this problem? i am confused since my teacher keeps calling ω the frequency and not the angular frequency...
