Impedance Calculation: Finding Capacitor Value w/ Phasor & ω

AI Thread Summary
To find the value of a capacitor using impedance and angular frequency (ω), the formula C = -j/ωZc is used, where Zc represents the capacitor's impedance in phasor form. There is no need to convert ω from radians per second to degrees per second for these calculations, as the standard unit for angular frequency in this context is radians per second. The calculations can be performed directly with ω in its given unit. The discussion confirms that maintaining ω in radians is appropriate for determining capacitor value. Understanding the relationship between impedance and capacitance is crucial for accurate calculations.

Homework Statement



I am trying to find value of a capacitor knowing capacitor impedance (Phasor) and ω (in rad/sec).

The Attempt at a Solution



Zc = -j/ωC
C = -j/ωZc

My question is do I have to convert the ω into degrees/sec before doing the calculations since Z(impedance) is in phasor form? I think i need to but just want to make sure.

Omega is in radians per second.
So the answer is No.
