Answer: in the symbol of an electric cell the positive terminal is represented by a longer line.
Which line represents the negative terminal in the symbol of an electric cell?
Answer: the symbol of the electric cell, the longer line represents the positive terminal and the thicker, shorter line represents the negative terminal.
Which symbol of the cell represents the positive end the long line or the short line?
(1) The symbol of a cell consists of two parallel lines, one thin and long, and the other thick and short. The long and thin line represents the positive terminal of the cell whereas the short and thick line represents the negative terminal of the cell. (2) The symbol of battery consists of two cells joined together.
Which side of cell is positive?
A cell or battery is drawn with a long line and a shorter line. The long line is the positive side (plus is longer). The short line is the negative side (minus is shorter).
Does an electric bell has an electromagnet?
An electric bell consists of one or more electromagnets, made of a coil of insulated wire around an iron bar, which attract an iron strip armature with a clapper.
What is positive and negative terminal?
Positive and Negative terminals
The electrode from which the electrons emerge is the negative terminal. It is also called the cathode. The electrode that receives electrons is the positive terminal.
What is inside an electric cell?
An electrical cell is an “electrical power supply”. It converts stored chemical energy into electrical potential energy, allowing positive charges to flow from the positive terminal to the negative one through an external circuit. … There are six tiny cells inside each rectangular 9V battery, for example.
Does bulb have positive and negative terminal?
An electric bulb has two terminals. The base of the electric bulb and the metal tip of the base are the two terminals of the bulb. One is called a positive terminal while the other is called a negative terminal. … These two terminals are fixed at their places in such a way that they do not touch each other.
What are the two effect of electric current?
Answer: The two effects of electric current are; heating effect and magnetic effect.
What is the longest line in the cell class 7?
A cell always has a positive and negative terminal. Hence it is represented by two vertical bars of different sizes. Since ‘electricity’ flows from the ‘positive terminal’ to the negative terminal the positive terminal is represented by the longer straight line.
What is the longest line in the cell?
The longer, thinner vertical line in the symbol of a cell represents the positive terminal.
What is the correct symbol of a cell?
A cell is represented symbolically using two lines – one is longer that represents the positive terminal and the other is shorter that represents the negative terminal.
What is the symbol of battery?
The symbol for a battery is made by joining two more symbols for a cell together. Think of what we usually call a single battery, like the type you put in a torch. In physics, each of these is actually called a cell . It is only when you have two or more of these cells connected together that you call it a battery.
Which of the following is the correct symbol of a cell?
Following Symbol is the correct symbol of cell… Plzzzz Mark it is the BRAINIEST answer of this question….
