Solution:
(15)
All the fans are connected in parallel. The voltage in between the two ports of each are equal. When the switch A is opened the source voltage can't reach to any of the fan.Hence no fan will operate if the switch A is opened.
Correct choice B. 0
(16) The diagram represents Device diagram
correct choice C. Device diagram
