What is the material used for the negative terminal in a dry cell?
In a dry cell, the negative terminal is typically made of zinc. Zinc serves as the anode, where oxidation occurs during the electrochemical reaction. This material is effective due to its ability to easily lose electrons, which is essential for the battery's function. Additionally, the zinc casing often serves as the cell's container, providing structural integrity.
What is the symbol for dry cell?
dry cell - a small Leclanche cell containing no free liquid; the electrolyte is a paste and the negative zinc pole forms the container of the cell; used in flashlights, portable radios, etc
What cell organelles are used to allow the dendrite to function?
Cell membrane, Nucleus, Cell wall, and axon terminal
What is difference between positive current and negative current which current is used for generation of electricity?
Positive current flows from the positive terminal to the negative terminal, while negative current flows in the opposite direction. In electrical systems, positive current is used for generating electricity as it represents the flow of electrons from negative to positive, which is the direction of conventional current flow.
What structure is responsible for digesting material for the cell?
Lysosomes are the organelles responsible for digesting material within the cell. They contain enzymes that break down macromolecules into smaller components that can be used by the cell.
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 is the direction of flow of current in a cell?
Current doesn't flow inside the cell. The cell is used to push current through an external circuit. The so-called "conventional" current flows out of the positive terminal of the cell, through the circuit, and back into the negative terminal of the cell. The confusing truth is that the actual physical carrier of current is the electron, which carries a negative charge. So the things that are actually moving and carrying the current through the circuit leave the dry cell from its negative terminal, physically flow through the circuit, and end up at the cell's positive terminal.

What do you disconnect first positive or negative?
Positive, because the negative terminal is usually used as the ground plane.

Which metal acts as negative terminal?
In electrochemical cells, the metal that acts as the negative terminal is typically the anode. In galvanic cells, this metal undergoes oxidation, releasing electrons that flow towards the cathode, which is the positive terminal. Common examples of metals used as anodes include zinc in a zinc-copper cell. However, the specific metal can vary depending on the type of cell and its materials.
What are uses of conventional current?
Conventional current is used in electronics to represent the flow of positive charge from the positive terminal to the negative terminal of a battery. It is used to simplify circuit analysis and design. It helps in understanding the direction of current flow in a circuit.
What is the symbol for a battery used in electrical circuits?
The symbol for a battery used in electrical circuits is a series of parallel lines representing the positive and negative terminals, with a longer line indicating the positive terminal and a shorter line indicating the negative terminal.
What are the colours of the positive and the negative terminals of the rheostat?
A rheostat is simply a variable resistor used to control current. It does not have a positive or a negative terminal.
Is the positive post on a car battery the ground?
Vehicle Electrical System GroundingFor MOST automotive electrical systems, NO, the positive battery terminal is NOT the ground. In most vehicular electrical systems the positive terminal is the "HOT" terminal, not the ground.The NEGATIVE TERMINAL IS ESTABLISHED/USED AS GROUND, in almost all vehicles.It is important to note that there are occasionally some exceptions to this standard, and you need to determine which grounding system is used on any vehicle BEFORE messing around with the electrical system.
