3.9 QUESTIONS
A large capacitor can absorb alternating currents in a circuit
without contributing significant amount of alternating voltages
in the circuit.
The total energy delivered to a capacitor carrying a voltage V
across it is ( )CV
2
J and this energy is stored in its electric
field. Stored energy in a capacitor is also given by ( C)Q
2
J
and QV/2 J. The capacitor will be able to deliver this stored
energy back to other elements in the circuit if called upon to
do so.
A single capacitor C
eq
can replace a set of n capacitors
connected in series as far as changes in charge, changes in
voltage and changes in total stored energy are concerned. ...
