Equations

Question 1

Electrical power =

Answer 1

I^2 x R

Question 2

Inductors impedance relates to frequency in that

Answer 2

Z= 2 x Pi x f x L

Electrical impedance is directly PROPORTIONAL to frequency for an inductor.

Question 3

Resistors impedance in relation to frequency

Answer 3

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

Question 4

Capacitor impedance in relation to frequency

Answer 4

Z= 1/2 x Pi x f x C

inversely proportional

Question 5

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

Answer 5

Energy dissipated is V2/R or I2R.
