Question

8 (ii)
A final observation that is unique to series circuits is the effect of removing a
bulb from a socket. If one of three bulbs in a series circuit is unscrewed from
its socket, then it is observed that the other bulbs immediately go out. Suppose
that all the appliances like the refrigerator, the toaster, oven, and overhead
light in a household kitchen were all connected in series. If current is cut from
any one of them, it is cut from all of them.
When one bulb is removed
from its socket, the other
bulbs in series "gooud.
Quite obviously, the appliances in the kitchen are
a) connected in series.
b) not connected in series.
c) not connected in parallel..
d) can not comment​

Answer 1

Answer:

A lot consists of 48 mobile phones of which 42 are good, 3 have only minor defects and 3 have major defect

Varnika will buy a phone if it is good but the trader will only buy a mobile if it has no major defect. One phone is

selected at random from the lot. What is the probability that it is (i) acceptable to varnika ? (ii) acceptable to the

trader

Answer 2

Answer:

So for series circuits, as more resistors are added the overall current within the circuit decreases. This decrease in current is consistent with the conclusion that the overall resistance increases. A final observation that is unique to series circuits is the effect of removing a bulb from a socket.
