Because the insulators that hold the cable up are designed to let the rain run off them. However there is some leakage during heavy rain which causes hissing and sometimes sparking.

Why when it rains hydro pole wires do not short circuit?
Because the insulators that hold the cable up are designed to let the rain run off them. However there is some leakage during heavy rain which causes hissing and sometimes sparking.
What two wires touching causes a short circuit?
the red wire and the blue wire A touching of two wires coming from any potential power source will cause a short circuit Short circuit relates to the quickest path back to the source with out any resistance to the current flow.
How many wires does a straight 220V circuit have?
A straight 220V circuit utilizes two wires per circuit.
What best describes the condition that occurs when bare wires in an electrical circuit accidentally touch causing more current to flow than the circuit can safely carry it will cause a fuse or circiut?
The correct name is a Short Circuit.
What happens if you move a switch and the circuit wires are not all connected?
When a switch is open (wires not connected) it is considered off. When a switch is closed it is considered on. If you move a switch and the wires are not connected the the circuit is open and current cannot run throughout the circuit to power the device.

When you will get to know that short circuit will happen?
1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?

What is the difference in an open circuit and a short circuit?
an open circuit is a circuit that does not complete the circle. an open circuit does not do the job as the electricity stands still a short circuit is a circuit that wires have crossed and the electricity takes the shortest path. and does not complete all of the points on the circuit
A screwdriver placed across two wires in a circuit creates a circuit?
Depending on where in the circuit the screw driver is placed it could be used as a switch or it could short the circuit out.
What happens in a short circuit occurs in an electric circuit?
A short circuit is a condition whereby a point or section of the circuit offer a short path for current to return to the power supply. It occurs when two or more points or sections of the circuit touches each others (but only and only if that results in drop in resistance to such an extent that it causes excessive current to flow through.
What may happen when two live wires touch each others?
short circuit
If a fuse melts does it create an open circuit a closed circuit or a short circuit?
If a fuse melts, it creates an OPEN circuit, meaning that no current flows in the wires because it is no longer a complete circuit.
Why don't AC input wires to a transformer just short circuit?
The resistance of the winding in the primary of a transformer constitutes a load. As long as there is resistance then there is no short circuit. A short circuit is considered no resistance which develops an instantaneous high current. That is why fuses and breakers are inserted into the circuit to open the high current flow under a short circuit condition.
How do you correct a short circuit?
A short circuit is repaired by first finding out where the short circuit occurred. On major faults usually the wires are removed and new wires are installed. On minor faults, the wire that shorted is separated from the offending wire or separated from the grounding medium. To put the conductor back into service the wire's insulation has to be brought back to the level of what the wire was when it was new. Once that is done the circuit can be re-energized.
What is the role of insulators such as plastic rubber and cloth covering wires and other conductors in a circuit?
Insulators are used to keep electrical currents in the circuit. If they do not follow the entire circuit, it would be a "short circuit".
Why is the secondary of a transformer a short circuit?
If you are saying that the secondary (output) winding on a transformer seems to be a short circuit, it is very likely to be low resistance and may only be a few ohms if you measure the resistance with an ohmeter. The only way it would actually be a short circuit is if something has been inserted which has shorted the wires or it has overheated and burnt through. In which case there should be an acrid smell. Or if you can see the wires you would see they were burnt. A short in the circuit it is powering could cause the transformer to overheat, burn out and short.
