A Capacitor Is Attached Across a Battery and Charged

question 32

Multiple Choice

A capacitor is attached across a battery and charged.Then the battery is removed leaving the capacitor charged.The positive lead of the capacitor is then connected to one lead of a previously uncharged identical capacitor,and then the other lead of the charged capacitor is connected to the other lead of the second capacitor.How does the energy E_o stored in the originally charged capacitor compare to the energy E_f stored in the connected capacitors?

• A)E_o < E_f
• B)E_o = E_f
• C)E_o = 2E_f
• D)E_o = 4E_f

In statistics, a measure of the overall variability in a dataset or the total amount by which values in a data set differ from the mean.

SSR

Sum of Squares due to Regression, a measure used in statistical models to quantify how well the model explains the variability of the data.

SSE

The sum of squared errors between observed and predicted values in regression analysis, indicating the discrepancy between data points and the regression line.

Standard Error
