Describe the relationship between the frequency and the capacitive reactance.
Discuss the following:
- Describe the relationship between the frequency and the capacitive reactance.
- What effect does frequency have on Ic and Vc for a fixed value of capacitance in this circuit?
- For a frequency of 1000Hz, what would be the effect of increasing the value of the capacitor on the current Ic and the voltage Vc?
- Why is it necessary to measure current in series with a device and voltage across it?
- Why is it necessary to determine Xc from measured values of current and voltage as opposed to measuring it directly with a digital multi-meter? (It may be helpful to perform research on the internet to gain more insight into the topic of this question.)
