Solutions


S1. Ans.(b)
Sol.

S2. Ans.(c)
Sol.

S3. Ans.(a)
Sol. The lightning conductor provides a very low resistance path between the top of the lightning conductor rod via a substantial strip of metal to the ground so that the current as a result of a lightning strike does not flow through the building to which it is attached.

S4. Ans.(a)
Sol. The material used for fuse elements must be of low melting point, low ohmic loss, high conductivity (or low resistivity), low cost and free from detraction.

S5. Ans.(b)
Sol. Repulsion is the surest test of the magnets, because a magnetic substance also has attractive property.

S6. Ans.(d)
Sol.

S7. Ans.(b)
Sol.

S8. Ans.(a)
Sol. A voltmeter is connected in parallel with a device to measure its voltage.

S9. Ans.(c)
Sol.

S10. Ans.(b)
Sol.
