Question

What is the relationship between capacitor and inductor to current, voltage and power?

Answer 1

The capacitor loves voltage and the inductor loves current.  If you get in the way of there love they will bite you.  When it comes to power it depends on if you want to keep it real or go with imaginary.

Good luck with your class.

Answer 2

ELI the ICE man

E for voltage

I for current

C for capacitive reactance

L for inductive (coil) reactance

X = reactance in Ohms (either inductive XL or capacitive XC)

ELI  Voltage (E) leads current(I) by upto 90 degrees in an inductive circuit (L)

ICE Voltage(E) lags current(I) in a Capacitive circuit (C)

You can have  effects from both capacitance and inductance combine into a net result.

Capacitive reactance is given a negative direction as it opposes Inductive reactance.

100 Ohms XL  - 50 ohms XC yeids a net 50 OHMS XL

The values of XL and XC are dependant upon frequency

XL = Square Root of (2 * Pi * freq * inductance)

XC = 1 / (Square Root of (2 * Pi * Freq * capacitance))
