Question
The energy stored incapacitor ST is ... the energy stored incapacitor UR.
QS + QT is... zero.
The electricfield betweenplates U and R is... that betweenplates S and T.
The voltageacross capacitor UR is ... that acrosscapacitor ST.
If the plateseparation for capacitor ST decreases,the energy stored in UR will ...
Hint: The electric field isproportional to the surface charge density on the plates and theplates of the two capacitors have the same area.
answers are either... less than, greater than, equal to, nochange, increase, or decrease
Thanks.
Hint: The electric field isproportional to the surface charge density on the plates and theplates of the two capacitors have the same area.
Explanation / Answer
The energy stored incapacitor ST is LARGER THAN the energystored in capacitor UR.
QS + QT isEQUAL TO zero.
The electricfield betweenplates U and R isLOWER THAN that betweenplates S and T.
The voltageacross capacitor UR is EQUAL TO Thatacross capacitor ST.
If the plateseparation for capacitor ST decreases,the energy stored in UR willDECREASE
