Answer Posted / viswanath

all capacitors hav equal
charge on both plates so
same potential .but bot
electrodes of battery in
most of the cases r not
of same potential.a
curent flows inside a
batery too.but actualy
conduction taks place in
cptor thru electrostatic
induction.and some btry
once discharge cant b
rechargd

If a control valve is hunting means means if we are giving 50% to the cv, the cv will open at 51% then slowly slwoly it will reaches 49% , so what to do for solve this problem. The cv is double acting and mounted for anti surge operation, it having 4 nos. volume booster, one sov, one positioner, etc..?
