Where does an electric short circuit occur?

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 the connection, a high current will flow, causing the delivery of a large amount of energy in a short period of time.

What does a short circuit occur?

A short circuit occurs when the current finds a way to bypass the appliance on a path that has little or no resistance—for example, where frayed insulation bares a wire and allows it to touch the frame of the appliance, so the current can flow straight to the ground.

What does an electric circuit occur?

1. When the two wires with one neutral charge or current possessed with another as live wire with current flowing through it, comes in contact with each other. Then high current flows through it than normal and thus short circuit occurs. 2.

Why does an electric short circuit occur Class 10?

When the insulation of live and neutral wires undergoes wear and tear and then touches each other, the current flowing in the circuit increases abruptly. Hence, a short circuit occurs.

How short circuit occurs in an electric fuse?

Answer: The connection of many electric wires to a single socket is called short circuit. The function of fuse in these situations is to cut off the rising load. In this situation, the fuse wire which is low in electrical resistance, melts due to rising current and breaks the circuit.

What causes a short circuit physics?

A short circuit is when there is a low resistance connection between two conductors that are supplying electrical power to a circuit. This would generate an excess of voltage streaming and cause excessive flow of current in the power source. The electricity will flow through a ‘short’ route and cause a short circuit.

What are the causes of short circuit class 7?

• Short Circuit: can occur due to direct touching of two wires, water seepage inside and electric circuit etc.
• Overload: Connection of many devices into single socket.
• Excessive current generated from power source.

What is short circuit Ncert?

A short circuit primarily occurs when two current carrying bare wires come in contact with each other. This results in the current flowing through the circuit reach a very high value that can cause danger and also result in a tripped breaker or blown fuse. Short circuits can occur in both DC and AC circuits.

What is a short circuit fault?

Well, a short circuit is the name given to a very particular electrical fault. This is when the electrical current does not pass through all of the wiring, and instead, chooses a shorter route. This is because electricity always wants to go back into the ground, and will take the most direct route.

When the short circuit condition occurs the current in the circuit?

When there is a sudden increase of current in the circuit then a huge amount of heat is generated at the fuse. Therefore option 3 is correct. Due to this heat, a spark is generated. Due to the huge amount of heat, the fuse melts and the circuit opened up.

What is short circuit fault?

What is miniature circuit breaker?

A Miniature Circuit Breaker is an electromechanical device designed to protect an electric circuit from over-current – A term to describe an electrical fault caused by either overload or short circuit. Back in the day we protected against over-current by using fuse wire (indeed, we used to sell it!).
