Answer:
(e) The circuit in which electrical contact at any point is broken.
Explanation:
becuae its an Open circuit
1)=Deliquescent means "becoming liquid or having the tendency to become liquid" (here). Liquescent means the same thing. You could use both of these words to describe butter or ice, but I am not sure about wax. Fusible means "capable of being fused or melted easily" (here), but seems to be used largely for metals....
2)=A circuit diagram (also known as an electrical diagram, elementary diagram, or electronic schematic) is a simplified conventional graphical representation of an electrical circuit. ... The diagram does not show the physical arrangement of components....
3)=A safety device is a piece of equipment such as a fire extinguisher, safety belt, or burglar alarm that reduces loss or damage from a fire, accident, or break-in....
4)=A short circuit is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an "open circuit", which is an infinite resistance between two nodes....
5)=In some programming languages, function overloading or method overloading is the ability to create multiple functions of the same name with different implementations....
6)=An MCB is an automatically operated electrical switch. Miniature circuit breakers are intended to prevent damage to an electrical circuit as a result of excess current. They are designed to trip during an overload or short circuit to protect against electrical faults and equipment failure.....
7)=Open-circuit voltage is the difference of electrical potential between two terminals of a device when disconnected from any circuit. There is no external load connected. No external electric current flows between the terminals....
8)=An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. ... When resistance is increased in a circuit , for example by adding more electrical components , the current decreases as a result...
a)=In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current....
