Class 6 science Electricity and circuits questions 2
Mark ‘True’ or ‘False’ for following statements:
a. Electric current can flow through metals.
b. Instead of metal wires, a jute string can be used to make a circuit.
c. Electric current can pass through a sheet of Thermocol.
Class 6 science Electricity and circuits Answers 2
a. True, Metals are good conductors of electricity, thus electric current can flow through metals.
b. False, Jute string cannot be used to make a circuit because it is an insulator.
c. False,a sheet of thermocol an insulator. Thus, electric current cannot pass through it.
b. False, Jute string cannot be used to make a circuit because it is an insulator.
c. False,a sheet of thermocol an insulator. Thus, electric current cannot pass through it.
Class 6 science Electricity and circuits questions 3
Explain why the bulb would not glow in the arrangement shown in the figure.
Class 6 science Electricity and circuits Answers 3
In the given arrangement, shown in the figure, the bulb would not glow because one end of the of the screw driver is made up of metal and the other end is made up of plastic which does not allow the electric current to flow through it. Thus, the circuit is disconnected due to presence of an insulator in between. Hence, bulb will not glow.

Class 6 science Electricity and circuits questions 4
Complete the drawing shown in the figure to indicate where the free ends of the two wires should be joined to make the bulb glow.
Class 6 science Electricity and circuits Answers 4
In the figure shown above the free ends are joined to make the bulb glow.
Class 6 science Electricity and circuits questions 5
What is the purpose of using an electric switch? Name some electrical gadgets that have switches built into them.
Class 6 science Electricity and circuits Answers 5
Switch is a simple device that is used to either break the electric circuit or to complete it. With the help of a switch, we can use an appliance according to our desire. Electric gadgets that have switches built into them are microwaves, freezes, automatic electric irons, toasters, patty makers.Class 6 science Electricity and circuits questions 6
Would the bulb glow after completing the circuit shown in the figure in the given below if instead of safety pin we use an eraser?
Class 6 science Electricity and circuits Answers 6
If instead of safety pin, an eraser is used, the bulb would not glow because eraser is an insulator which does not allow the electric current to pass. Hence, bulb will not glow.

Class 6 science Electricity and circuits questions 7
Would the bulb glow in the circuit shown in the figure?Class 6 science Electricity and circuits Answers 7
In the given figure, the bulb will not glow the two terminals of the connecting wire of the cell are connected to the same terminal of the bulb.Class 6 science Electricity and circuits questions 8
Using the “conduction tester” on an object it was found that the bulb begins to glow. Is that an object a conductor or an insulator? Explain.
Class 6 science Electricity and circuits Answers 8
The object is a conductor because if the object is good conductor of electricity, then electric current will pass through the conduction tester and the bulb will glow.
