Q:

What causes a short circuit?

A:

Quick Answer

A short circuit is caused when two or more uninsulated wires come into contact with each other, which interferes with the electrical path of a circuit. The interference destabilizes normal functioning of electricity flow. The resistance generates a lot of heat in the wires and can lead to a fire.

Full Answer

A short circuit exists when positive and negative terminals of a current connect on a low-resistance conductor. This contact causes more electrical energy to be produced within a short time. Since a short circuit can lead to unintentional fires, electrical devices are installed with fuses or circuit breakers to prevent the surge of destructive electrical energy.

  • Q:

    What happens to the current in a short circuit?

    A:

    When a short circuit occurs, electrical current experiences little to no resistance because its path has been diverted from its normal direction of flow. This in turn produces excess heat and can damage or destroy an electrical appliance. It can also create a fire hazard and an electrical shock hazard if left unattended

    What causes a short in an electrical outlet?

    A:

    A short circuit in an electrical outlet occurs if the bare metal of a hot wire touches the bare metal of the neutral or the ground wire. While referred to as a short in an outlet, it often occurs in the wires behind the circuit.

    What causes static?

    A:

    Static is caused by the transfer of electrons from one object to another. Transferring electrons can create an imbalance in the charge of the atoms in the two objects, making one more positive and one more negative, effectively attracting them to each other.

    What causes fluctuation in line voltage?

    A:

    Fluctuation in line voltage can be caused by loose or corroded lines in either the house or the power lines, according to Northpower. It is also caused by insufficient wiring installation and even lightning strikes on or in the vicinity of power lines.
