Answer:
Draw a circuit diagram showing the cell, switch and a bulb.
Hint: To draw a circuit diagram showing cell, bulb and switch, we must know what all these devices are and what are their functions. These are basic devices that we use in our household as well. Cells are used in remotes, clocks etc. Bulb is used as a source of light. Switch is used to turn on and off electrical appliances such as mixers, televisions etc. In a circuit, these three components are connected through wires.
Explanation:
CELL: A cell is a device which uses chemical reaction to produce current. This chemical reaction is made by producing electricity. When one or more cells are combined, a battery is formed. A single cathode and anode together forms a cell and these electrodes are separate by an electrolyte to produce current and voltage. It converts chemical energy into electrical energy.
SWITCH: Switch is a device used to interrupt the flow of electricity. In simple words we can say, it is used to turn on or turn off electric appliances such as fans, washing machines, geysers etc. There are two types of switches. They are Mechanical switches and Electrical signals.
BULB: When a light bulb is connected to a power supply, current flows from one metal contact to the other. It has a metal filament fixed inside. When enough current is passed through the filament, the filament heats up and emits photons which are in the form of visible light.
Note:
When the switch is on, it means the circuit is closed and current is flowing. When the switch is off, it means the circuit is open and flowing current has stopped. So, when the switch is on, the cell pushes current to the bulb and it glows. Filament of an electric bulb is made up of tungsten. Cells are mostly used for tasks which require less energy such as lamps, clocks etc.
when you realise you read this chapter I this class.
I hope that u can atleast cuz I would only be able to explain
Ans1. An electric cell is a device, which converts chemical energy into electrical energy. It has two terminals, which are made up of metal: one terminal is positive, while the other one is negative. When the two terminals are connected to an electrical device, electric current flows through it.
Ans 2 An electric bulb refers to an electric lamp which consists of a translucent or transparent glass housing. It is also known as a light bulb. This simple device has been used for the purpose of illumination for more than a century. Electric bulb refers to a device which produces light on the application of electricity.
Ans3. The electric circuits are closed-loop or path which forms a network of electrical components, where electrons are able to flow.
Ans 4. (You can draw can you?)
I gave you the answers but I am not able to draw the diagrams here, sorry for that
Can you pls mark me the brainliest
