Question

B. Answer the following questions orally.
1. Why do we need circuit diagrams?
2. Is there any purpose in using standard symbols in circuit diagrams?
3. What are the possible dangers of not using a fuse in an electric circuit?​

Answer 1

Answer:

1. A drawing meant to depict what the physical arrangement of the wires and the components they connect is called "artwork" or "layout" or the "physical design." Circuit diagrams are used for the design (circuit design), construction (such as PCB layout), and maintenance of electrical and electronic equipment.
2. By using the various standard circuit symbols in schematic diagrams, it is possible to create a diagram that is not only easy to read, but also open to less mis-interpretation than if non-standard symbols are used.
3. If fuse is not here in the circuit,then by any chance if the current passes through the circuit larger than the required value,it can cause severe damage to the appliances and can get the house on fire.
