Question

When we switch on the light, it appears almost immediately because electrons drift inside the metal very fast. True False Two lamps connected in series experience the same current. True False A conductor moving in magnetic field develops potential difference. True False Constant current produces magnetic field that changes with time. rue False Magnetic field of the induced current directed the same way as the change of the magnetic flux. True False The circuits have AC current to increase power loss during transmission. True False

Explanation / Answer

5. False , Because, while the drift velocity is slow, the signal velocity is enormous.

6. True, because when connected in series, there is only one path and by kirchoff's first law , both will have same current.

7. True, because the electon will experience magnetic force and will accumulate in one end leading one end to be negetively charged and other end to be positively charged, thus potential difference.

8. False, it will be constant magnetic field.
