Question

Symbol of electric cell is-

(A).

(B).

(C).

(D).

Answer 1

Hint: A cell consists of a positive electrode and a negative electrode. Hence, the symbol of a cell is written in such a way that a positive electrode and negative electrode could be shown symbolically with the ability to differentiate which one is positive and which one is negative.

Complete step by step answer:
(A).

In this symbol, the inner part of the circle looks like a tungsten wire inside the bulb and the circle should be the outline of the bulb. This symbol represents a bulb in the circuit.

(B).

A cell has two electrodes. Anode and cathode. Or in simple terms, positive and negative electrodes. This diagram shows two straight vertical bars, which represent electrodes. The larger bar represents positive sign and the smaller bar represents negative sign. So this is the symbol of a cell.
(C).

Every circuit needs to have a switch. So that we could shut it down when we are not using it. To show that the circuit is not working (it is open) we need to show a gap in the circuit to express that the current is not flowing. The symbol above shows that gap. And the line that is drawn at a certain angle above the left point shows that the circuit can be closed by moving that line below to touch the other point in the circuit. This diagram represents a switch. To be specific. Open switch.
(D).

Clearly, it is a closed switch.
Therefore, from the above explanation, the correct answer is, option (B)

Note: Every symbol created, is usually created in such a way that they could be easily identified. That is why, the symbols are usually written in such a way that they could express what they represent.
