Q1. DIFFERENTIATE BETWEEN:-
A. FUSE AND MCB
B. CFL AND ELECTRIC BULB
Answers
Answer:
difference between fuse and mcb
fuse..Fuses other than rewireable fuses cannot be reused.Fuses acts faster than MCB. Typical tripping time 2ms.
mcb...Miniature circuit breakers can be reused after the clearance of faults.Tripping time for MCB is 20ms
difference between CFL and electric bulb
.CFLs: Compact Fluorescent Lights
The big difference between CFLs and incandescent bulbs is how much energy it takes to use them over time. CFLs use about 70% less energy than incandescent bulbs. They also last years longer than traditional bulbs, and only cost about a dollar more per bulb.
electric bulb..An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation.

Answer:
A, Fuse is an electrical device that self-destructs and stops the current flow in a circuit whenever the current exceeds the predefined value. MCBs are resettable circuit protection device that, on the occurrence of faults, stops the current flow in a circuit.
B, CFLs produce light differently than incandescent bulbs. ... In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.
