A 0120 PF Parallel-Plate Capacitor Is Charged to a Potential Difference

question 36

Multiple Choice

A 0.120 pF parallel-plate capacitor is charged to a potential difference of 10.0 V and then disconnected from the battery. A cosmic ray burst creates 1.00 × 10⁶ electrons and 1.00 × 10⁶ positive charges between the plates. If the charges do not recombine, but reach the oppositely charged plates, by how much is the potential difference between the capacitor plates reduced?

• A) 1.33 V
• B) 7.34 V
• C) 8.67 V
• D) 1,330 V
• E) 8,670 V

Definitions:

External Validity

The extent to which research findings can be generalized to settings or groups outside the study.

Confounding Variables

External factors that can influence both the dependent and independent variables, potentially biasing the results of a study.

Independent And Dependent Variables

In experimental research, the independent variable is the factor that is manipulated to see its effect on the dependent variable, which is the outcome being measured.

Ratio Level

A measurement scale that has a true zero point and equal intervals, allowing for the calculation of ratios.
