Question

(4) How does the short Circuit form? What is its effect?​

Answer 1

Answer:

A common type of short circuit occurs when the positive and negative terminals of a battery are connected with a low-resistance conductor, like a wire. With a low resistance in theconnection, a high current will flow, causing the delivery of a large amount of energy in a short period of time.

Answer 2

Answer:

Short Circuit Could be caused by

1.Faulty Circuit Wire Insulation.

2.Old or damaged insulation may allow neutral and hot wires to touch, which can cause a short circuit. ...

3.Loose Wire Connections. ...

4.Faulty Appliance Wiring. ...

5.Circuit Breakers or Fuses. ...

6.Ground-Fault Circuit Interrupters (GFCIs) ...

7.Arc-Fault Circuit Interrupters (AFCIs)

The effect of short circuit is

When short circuit happens, the current in the system increases to high value while the system current decrease to a low value. The heavy current due to short-circuit causes excessive heating which may result in fire or explosion.
