Asymbol from a circuit diagram is shown

The given picture shows a light bulb.

Explanation:

The circuit diagram is the pictorial form to represent electrical devices. There are many elements of a circuit i.e. resistors, transistors, voltmeter, ammeter, switch etc.

In this case, we need to write the name of the given symbol. The electrical symbols are given in order to show the elements of a circuit. The given figure shows a light bulb.

Hence, the correct option is (b) "a light bulb".

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
