# Equations Flashcards

1

Q

Electrical power =

A

I^2 x R

2

Q

Inductors impedance relates to frequency in that

A

Z= 2 x Pi x f x L

Electrical impedance is directly PROPORTIONAL to frequency for an inductor.

3

Q

Resistors impedance in relation to frequency

A

Electrical impedance is independent of frequency for a resistance (Z= R).

4

Q

Capacitor impedance in relation to frequency

A

Z= 1/2 x Pi x f x C

inversely proportional

5

Q

In an electrical circuit, the current dissipated is calculated by?

A

Energy dissipated is V2/R or I2R.
