Question

A 3,.50-uF capacitor is charged by a 12.0-V battery. Iti disconnected from the battery and then connected to an uncharged 4.50-pF capacitor (see). C) 1/2 https://session.masteringphysics.com/myct/assignmentPrintView?assignmentID-5798758 Part A Determine the total stored energy before the two capacitors are connected. Express your answer using three significant figures and include the appropriate units. ANSWER: PEinitial- Part B Determine the total stored energy after they are connected. Express your answer using three significant figures and include the appropriate units. ANSWER: PEfinal = Part C What is the change in energy? Express your answer using three significant figures and include the appropriate units. ANSWER:

Explanation / Answer

Part A:

Total stored energy before the two capacitors are connected, E = (1/2)*C*V^2 = 0.5*3.50x10^-6x12^2

= 2.52 x 10^-4 Joule

Part B:

Total energy shall be conserved.

So, total stored energy after the capacitors are connected = 2.52 x 10^-4 J

Part C:

Therefore, change in energy = 0 J.
