What material in dry cell has a negative charge?
carbon rod
What are electrodes made out of?
The positive electrode is a graphite rod (elemental carbon).
What are the chemicals in dry cell batteries and what is their purpose?
dry cells don't have liquids inside but they do have some sort of a paste of zinc chloride and ammonium chloride dissolved in water. The positive terminal is usually a carbon rod or graphite rod surrounded by a mixture of manganese dioxide and carbon powder. the negative terminal is the packaging, and is made of zinc.you should just look it up on wikipedia, and you will save yourself a lot of time...
Is carbon rod magnetic?
No, Carbon is diamagnetic.
Is the eye cell a cone cell?
Yes it is and there is also a rod cell
What rod forms the positive terminal of a dry cell?
carbon rod
In a dry cell the carbon rod releases electrons and becomes the positive or negative terminal?
In a dry cell, the carbon rod is the positive terminal, or anode.
What material in dry cell has a negative charge?
carbon rod
What will you find inside a dry cell of a battery?
carbon rod
The zinc rod forms the positive terminal of a dry cell?
No, it is the carbon
The positive terminal of a dry cell battery identifies the location of the carbon rod?
yes
What are the parts of a dry cell?
Break the cell from bottom with a hammer , take out the MGO2 from inside , hit the upper part of the cell and remove the carbon rod from it. make the paste of the mgo2 with water and fix carbon rod and zinc plate as cathode and anode in a box and connect their wires in the galvanometer and you will get the current deflection on it
What kind of material is used to make the positive electrode of a dry cell?
The positive electrode is a graphite rod (elemental carbon).
What causes current to flow in dry cell?
an acid paste reacts with the metal casing which causes electrons to flow to a carbon rod
Describe briefly the method a dry cell battery uses to produce voltage?
A dry cell battery uses two electrodes made of dissimilar metals inserted in a paste like electrolyte. The container of a dry cell battery is made of zinc which is the negative electrode. The carbon rod in the middle of the dry cell battery is the positive electrode. The space between the electrodes is filled with an electrolyte usually manganese dioxide paste. the paste causes a chemical reaction between the carbon rod and the zinc case.
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 difference between a wet cell and a dry cell?
* A "dry-cell" battery is essentially comprised of a metal electrode or graphite rod (elemental carbon) surrounded by a moist electrolyte paste enclosed in a metal cylinder as shown below. * In the most common type of dry cell battery, the cathode is composed of a form of elemental carbon called graphite, which serves as a solid support for the reduction half-reaction. * At the center of each dry cell battery is a rod called a cathode, which is generally made of metal or graphite and is surrounded by an electrolyte paste. The cathode and electrolyte paste are wrapped in paper or cardboard.
