2) Tara after completing her exams, went to her grandmother's
house along with her younger brother Rahul. One day, Rahul
came home after playing and switched on the fan as well as air
conditioner. At the same time, his grandmother was preparing
a milkshake for him using a mixer. Suddenly, there was a big
sound and the electricity of the house got shut down. Tara then
called an electrician. He said the main reason of supply to shut
down was overloading. Both Tara and Rahul asked few ques
tions to the electrician as given below. What answers would
the electrician had given to these questions.
a) What is overloading?
b) How can the effects of overloading be avoided?
c) Is overloading and short circuiting circuiting same ? When
does short circuiting take place?
d) What happens to the resistance of the circuit during a
short circuit?
e) What happens to the flow of electric current during a short
circuit?
Answers
Answer:
1. The pressure for using electricity.
2. By not using heavy electrical appliances at the same time.
3. No. Short circuit takes place when the circuit is damaged.
4. It gets damaged.
5. It stops.
A). Overloading is a concept used to avoid redundant code where the same method name is used multiple times but with a different set of parameters. The actual method that gets called during runtime is resolved at compile time, thus avoiding runtime errors.
B). The effect of overloading can be avoided by few precautions: (a) Don't use more power things than the capacity of the source. (b) Always use good material like Fuse, MCB, Electric Wire, Plugs, etc
C). Overloading occurs when an electric circuit draws more current than the permitted value and short circuiting occurs when the ends of a circuit are connected by a conductor of very low resistance as compared to that of circuit.
D). A short circuit is simply a low resistance connection between the two conductors supplying electrical power to any circuit. This results in excessive current flow in the power source through the 'short,' and may even cause the power source to be destroyed.
i hope this answer helps..
