Telanagana State Board Class 6 Science Chapter 12 Simple Electric Circuits Solution:
(1)
An electric circuit provides a complete path for electricity to flow between all and the bulb. (It consists of a all (power source) a bulb and connecting wires).
A similar circuit exists for an electric bulb which we use in our houses.
The two electric supply wires called live and natural are connected to the two terminals of the bulb through a switch.
When the switch is closed (put on) the circuit provides complete path of electricity.
(2)
Inside View of a torch – light:
Torch light is used as a source of light. The parts of a torch light are hollow cylindrical barrel, cells, bulb, switch, glass cover and metal spring.
(3) Ans. (c) Filament.
(4) Ans.
Conductor | Insulator |
Water | Plastic Pen |
Pencil lead | Dry cotton cloth |
Wet cotton cloth | Dry wood |
Wet wood |
(5) Ans.
(i) What is he doing?
(ii) Why is he wearing gloves on his hand?
(iii) How much rubber gloves help him?
(iv) Is it sufficient to wear gloves on his hand?
(6) The lid of the torch is not tightly screwed and the circuit opens. So the bulb does not glow.
Niharika might have put an insulation in between the two cells.
The switch level has been bent in such a way that it did not touch the bulb, this makes the circuit open.
(c) The student can connect the circuit as shown in and find the bulb glowing.
(8)
(i) The bulb in the torch through the switched is in on position.
(ii) The reason is the cells arranged in the torch are not correctly placed.
(iii) The positive terminals of the two cells are side by side. So current does not flow.
(iv) One of the cells in the torch should be put in the reverse.
(9)
(10)
*The cell used might have been totally discharged.
*The bulb taken might have been fused
*The switch arranged may not be in touch with the wires as expected.
*There may be a break in the continuity of the wires taken.
(11) Ans. Edison was of an inquisitive nature and he learned science by performing experiments himself.
An intelligent scientist like Edison had to work hard for many years before he could make a bulb that work. First of all, he passed electricity through a thin, thread-like platinum wire. He noticed that the wire did give out light after being heated, but it burned out, after only a few seconds. Edison then thought that if the air surrounding the wire coil was removed then, the wire would not burn out so quickly. He made a glass casing and casing and fitted a filament of platinum wire in it. Then he removed the air from glass casing and passed an electricity current through the wire and the bulb lit up.
(12) Ans. Washing machine and grinder.
Electricity fan and electric iron
Television and tape recorders
Computers and motors to lift water
Heaters, Generators
(Electric)
Current through the wire and the bulb lit up.
(13) Ans. Basically electric energy is the energy that can be converted into any form of energy. So these, energy tamed to provide comfort to us through various applications. The present struggle of many scientists is to convert many energy resources into electricity so that if it provides service without pollution.
Had not this invented we would be living like our ancient uncivilized people. This has brought a lot of revolution in the life style of human beings.
(14) Ans.
Works with cell as a source |
Works with electricity current as a source | Works with both car and electric current as a source |
Torch | Television |
Laptops |
Radios |
Refrigerator | Mobile phones |
Alarm and wall | Fans |
Hair trimmers |
Clocks |
Tube lights | Transistors |
Remote controls |
Air conditioners |
|
Children toys |
Mixer grinder | |
Micro wave oven |
(15) In first circuit connection the bulb does not glow. Because there positive and negative terminal does not connected so the bulb don’t glow.
In rest very cases bulb flows. Because connect positive and negative terminal correctly the bulb glows.
(16) Match the following:-
