The 60-Hz ac source of the series circuit shown in the figure has a voltage amplitude of
120 V.The capacitive reactance is 790 Ω,the inductive reactance is 270 Ω,and the resistance is 500Ω. (a)What is the capacitance of the capacitor?
(b)What is the inductance of the inductor?
Coefficient Alpha
Coefficient Alpha, often denoted as Cronbach's alpha, is a measure used to assess the reliability, or internal consistency, of a set of scale or test items.
Internal Consistency Reliability
A measure of how well the items in a test measure the same concept or construct, indicating the extent to which all items in a test contribute equally to the final score.
Parallel Forms Reliability
The consistency of scores on two different but equivalent forms of the same test, assessing the consistency of results over different versions of instruments.
Test-Retest Reliability
The consistency of a measure or test over time when administered to the same individuals under identical conditions.
