Test: Electricity and Circuits - Question 4

----------- is the positive terminal of an electric cell.

Detailed Solution for Test: Electricity and Circuits - Question 4

Metal cap is the positive terminal of the electric cell. The Metal disc is the negative terminal.

Test: Electricity and Circuits - Question 5

The tiny coiled metal wire present inside the bulb is called____________.

Detailed Solution for Test: Electricity and Circuits - Question 5

An incandescent light bulb has a small thin wire with two bigger wires holding it up. This wire is called a filament. The filament is the part of the light bulb that produces light. Filaments in incandescent light bulbs are made of tungsten.

Test: Electricity and Circuits - Question 6

 _______ is an electric device which easily closes or opens an electric circuit.

Detailed Solution for Test: Electricity and Circuits - Question 6
The electric device that easily closes or opens an electric circuit is an electric switch.

Explanation:
- Electric switch: An electric switch is a device that is used to control the flow of electricity in a circuit. It can easily open or close an electric circuit by interrupting or allowing the flow of current.
- Filament: A filament is a wire or thread that is heated to produce light in an electric bulb. It is not responsible for opening or closing an electric circuit.
- Electric bulb: An electric bulb is a device that produces light when an electric current passes through its filament. It is not designed to open or close an electric circuit.
- Electric cell: An electric cell is a device that converts chemical energy into electrical energy. It is not used to open or close an electric circuit.
Therefore, the correct answer is Electric switch (C) as it is specifically designed to easily open or close an electric circuit.
Test: Electricity and Circuits - Question 7

Electric energy is produced from the____________ within the cell.

Detailed Solution for Test: Electricity and Circuits - Question 7

In simple cell battery converts chemical energy into electricity. The chemical reaction produces electrons, which then collect at the negative terminal of the battery. When there is a connection between the positive and negative terminal, the electrons flow to the positive terminal.

Test: Electricity and Circuits - Question 8

The electric current in a closed circuit always flows from the ___________terminal of the electric cell to the ______terminal.

Detailed Solution for Test: Electricity and Circuits - Question 8

The electric current always flows from the higher potential to lower potential. The positive terminal of an electric cell is at higher potential with respect to its negative terminal. Hence, in the given circuit, the current will flow from terminal P to terminal N. 

Test: Electricity and Circuits - Question 9

The central _____________of an electric cell is always positive.

Detailed Solution for Test: Electricity and Circuits - Question 9

Positive charge is up and the current is going to the negative charge. That's why the center terminal of an electric cell is always positive.

Test: Electricity and Circuits - Question 10

Kerosene oil is an example of _______________.

Detailed Solution for Test: Electricity and Circuits - Question 10

Petrol and kerosene oil have very low electrical conductivity and hence they are poor electrical conductors (i.e. insulators).
