Vedclass · Answer

(C) The appliances are connected in parallel to the $220\, V$ main line.In a parallel circuit,the total current $I_{total}$ drawn from the source is the sum of the individual currents drawn by each appliance.$I_{total} = I_{iron} + I_{TV} + I_{refrigerator}$$I_{total} = 5\, A + 3\, A + 2\, A = 10\, A$.The fuse wire is a safety device that protects the circuit from overloading. Its current capacity must be slightly greater than the total rated load current to prevent unnecessary blowing of the fuse during normal operation.Since the total current is $10\, A$,a fuse of $15\, A$ is the most appropriate choice among the given options to handle the load safely.

An electric iron draws $5\, A$,a $TV$ set draws $3\, A$,and a refrigerator draws $2\, A$ from a $220\, V$ main line. The three appliances are connected in parallel. If all three are operating at the same time,the fuse used should be of ............. $A$. (in $, A$)
