Not an already blown bulb, but when an incandescent bulb blows it sometimes arcs where the filament breaks, and this arc can extend across the terminals, causing a short circuit. This will blow the breaker.

The potential will be the same at any point before the bulb and any point after the bulb before the gap. Therefore, the potential at A is the same as the positive terminal of the battery, and the potential at B is the same as the negative terminal. The potential difference between A and B will be same as the battery.

When you short ciruit the bulb, the current flowing in the shorted leg increases a lot – the battery will get flattened quickly but would’nt get hot. The other leg would be completely unaffected – the bulb would remain on as before.

Since the circuit is open, the circle of flow of electrons is incomplete. There is no continuous flow to maintain glow of light. The open circuit nullifies potential difference between the 2 points. So the electron flow is cancelled and electrons fail to pass through the bulb.

Answer. When a short-circuit occurs, the current in the system increases to an abnormally high value while the system voltage decreases to a low value. The heavy current due to short-circuit causes excessive heating which may result in fire or explosion.

A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion.

Short circuits are abnormal electric connections which allow additional electricity to run through your switches, appliances, and outlets. The additional heat generated by the extra electricity can also cause fires in the affected wires and reach the flammable parts of your home.

A short circuit is an electric circuit offering little or no resistance to the flow of current. Short circuits are dangerous with high voltage power sources because the high currents encountered can cause large amounts of heat energy to be released.

depends a bit on the type of battery – even a brief short can cause a Li-ion battery to discharge to below a certain voltage that kills the cell and longer shorts can cause more dramatic effects.

DON’T DO THIS, but if you connect a wire directly from the positive to the negative side of a power supply, you’ll create what is called a short circuit. This is a very bad idea. This could cause your wire to burn up, damage the power supply, drain your battery, or other exciting things.

If your battery is reading 0 volts, chances are the battery experienced a short circuit. If the battery cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell. If the battery is fully charged (according to the battery charger) but the voltage is 12.5 or less, the battery is sulfated.

The thing that short circuited will most likely melt. If not, it will weld itself and can not be removed. If battery is very capable it will continue until it explodes/ruptures or melt. It will be ruined forever if short circuit lasts for long like half a minute.

The short may temporarily evaporate but the damage to the separator material remains. The repaired cell often exhibits a high self-discharge and the short frequently returns. Replacing a shorted cell in an aging pack is not recommended unless the new cell is matched with the others in terms of voltage and capacity.

A short circuit may be in a direct- or alternating-current (DC or AC) circuit. If it is a battery that is shorted, the battery will be discharged very quickly and will heat up due to the high current flow. Short circuits can produce very high temperatures due to the high power dissipation in the circuit.

The multimeter, set to measure continuity, can be used in a similar way. Disconnect battery positive, set the positive probe on the load side of the fuse, clamp the negative probe to battery negative. If there is a short circuit, the test light will illuminate or the multimeter will beep. Now, divide and conquer.

Some electrical problems are more subtle than others, but keep an eye out for the following warning signs so you can get ahead of them:

• #1 – Burning Smells.
• #2 – Dim Lights.
• #3 – Stereo System or Other Electronics Not Working.
• #4 – Corrosion on the Battery Cables or Terminals.
• #5 –The Engine Won’t “Turn Over”
