No. It seems Zinc would always act as the negative terminal. Anode and Cathode are the terms used when we connect an external electrical source to the device. If positive terminal of an external battery is connected to the electrode then that electrode is named as ANODE. If negative terminal is connected then it is named as CATHODE.
In case of chargable device, while discharging say P acts as negative terminal. Then while charging this negative terminal would be the anode.
So if the device is a chargable one and Zn acts as negative terminal while delivering current to the external load, then the same zn would acts as anode while charging.

Is copper an anode or cathode?
the zinc shell. good luck with webassign!
What do you call the electrode connected to negative terminal of a cell?
The negative terminal is called the anode
What will happen when electrolysis of dilute sodium chloride solution using copper and zinc electrode?
Usually hydrogen will evolve from the cathode and oxygen from the anode, but if zinc is the anode, it may dissolve to produce zinc ions in the solution either instead of or along with oxygen evolving.
Why is use of a sacrificial anode considered to be a way to prevent corrosion?
The anode creates a galvanic cell in which magnesium or zinc will be corroded more quickly than the metal of, let's sa a tank.
What are zinc blocks used for?
As a sacrificial anode on boat hulls and oil drilling rigs etc to prevent corrosion
What is carbon rod connected to the negative terminal of the battery?
The negative terminal of a carbon/zinc cell is connected to the zinc cup that functions as the cathode. The carbon rod is the anode (positive).
What is the one type of handy voltaic cell consisting of a zinc container which acts as the anode and a carbon cathode?
battery
Which electrode in the anode is galvanic cell?
Zinc is the anode.
Why is zinc negative amd copper positive?
Zinc is more electronegative than copper. As a result, zinc acts as the anion(anode), while copper loses electrons and becomes positive (cathode). Electrons flow from the zinc to the copper ( - to +)
Is copper an anode or cathode?
the zinc shell. good luck with webassign!
What is common anode?
A Common Anode Means A Negative Terminal Of The Battery.
The terminals of a diode are called the?
anode positive potential cathode negative potential
What is the positive terminal of a diode known as?
It is called the positive + terminal or post, just like you list. Electrons flow for the negative - to the + terminal contrary to popular belief.Another AnswerAs electrons flow through the external circuit from anode (negative terminal) to the cathode (positive terminal) , then the answer is 'cathode'.
How do you calculate zinc anode quantity in water ballast tank?
current= area of surface x current density required / 1000 , weight of zinc anode = current x life of anode (4yrs) x 8766 / 780
What do you call the electrode connected to negative terminal of a cell?
The negative terminal is called the anode
What is the negative battery terminal called?
Cathode
Why is there a plus and minus of batteries?
plus is the positive terminal (cathode) minus is the negative terminal (anode)
