An Air-Filled Parallel-Plate Capacitor Is Constructed with a Plate Area

question 74

Short Answer

An air-filled parallel-plate capacitor is constructed with a plate area of 0.40 m² and a plate separation of 0.10 mm. It is then charged to a potential difference of 12 V? (ε₀ = 8.85 × 10^-12 C²/N ∙ m²)
(a) How much charge is stored on each of its plates?
(b) How much energy is stored in it?

Definitions:

Non-Directional

Pertaining to a hypothesis that does not specify the direction of the expected relationship between variables, only that one exists.

Sample Size

The number of observations or units in a subset of a population used in statistical analysis.

Correlational Research

A type of non-experimental research method used to determine, describe, and predict how variables are naturally related in the real world without any experimental manipulation by the researcher.

Two-Tailed

Pertaining to tests of statistical significance that consider both directions of effects, allowing for the assessment of the possibility of both positive and negative differences.
