The NCERT Solutions in English Language for Class 6 Science<\/a><\/span> Chapter – 12 (Electricity and Circuits) <\/strong>has been provided here to help the students in solving the questions from this exercise.<\/span><\/p>\n

Chapter – 12 (Electricity and Circuits)<\/span><\/strong><\/span><\/h2>\n

1. Fill in the blanks :
\n<\/strong>(a) A device that is used to break an electric circuit is called _______________.
\n<\/strong>(b) An electric cell has _______________ terminals.<\/strong><\/span><\/p>\n

Answer –
\n<\/strong>(a) A device that is used to break an electric circuit is called\u00a0switch<\/strong><\/span>.
\n(b) An electric cell has\u00a0two<\/strong><\/span>\u00a0terminals.<\/span><\/p>\n

2. Mark \u2018True\u2019 or \u2018False\u2019 for following statements:
\n<\/strong>(a) Electric current can flow through metals.
\n(b) Instead of metal wires, a jute string can be used to make a circuit.
\n(c) Electric current can pass through a sheet of thermo Col.<\/span><\/p>\n

Answer –
\n<\/strong>(a) Electric current can flow through metals. (True)<\/strong>
\n(b) Instead of metal wires, a jute string can be used to make a circuit. (False)<\/strong>
\n(c) Electric current can pass through a sheet of thermo Col. (False)<\/strong>

3. Explain why the bulb would not glow in the arrangement shown in Fig. 12.13.
\n\"NCERT<\/strong>Answer –\u00a0<\/strong>The bulb does not light up in the arrangement because the circuit is not complete.<\/span><\/p>\n

4. Complete the drawing shown in Fig 12.14 to indicate where the free ends of the two wires should be joined to make the bulb glow.
\n\"NCERT<\/strong><\/span>Answer –\u00a0\"NCERT<\/strong><\/span><\/span><\/p>\n

5. What is the purpose of using an electric switch? Name some electrical gadgets that have switches built into them.<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>Electric switch is used to make electric circuit open or closed for a particular appliance and hence with the help of a switch we can use an appliance according.<\/span><\/p>\n

6. Would the bulb glow after completing the circuit shown in Fig. 12.14 if instead of safety pin we use an eraser?<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong><\/span>\u00a0<\/strong>No, the bulb will not glow as eraser is an insulator.<\/span><\/span><\/p>\n

7. Would the bulb glow in the circuit shown in Fig. 12.15?
\n\"NCERT<\/strong>Answer –\u00a0<\/strong>Yes, the electric circuit is closed so the bulb will glow.<\/span><\/p>\n

8. Using the \u201cconduction tester\u201d on an object it was found that the bulb begins to glow. Is that object a conductor or an insulator? Explain.<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>Yes, if the object is good conductor of electricity then current will pass through conduction tester and the bulb will glow. Hence the object will be a conductor of electricity.<\/span><\/p>\n

9. Why should an electrician use rubber gloves while repairing an electric switch at your home? Explain.<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>An electrician uses rubber gloves while repairing an electric switch at your home because rubber gloves are insulators. This protects him from avoiding electric shocks.<\/span><\/p>\n

10. The handles of the tools like screwdrivers and pliers used by electricians for repair work usually have plastic or rubber covers on them. Can you explain why?<\/strong><\/span><\/p>\n

Answer –\u00a0<\/strong>Wood or plastic are insulators and do not allow electricity to pass through them. Hence electricians must use screwdrivers, with wooden or plastic handles, when they carry out repairs to avoid electric shocks.<\/span><\/p>\n
