In summers, materials tend to expand due to increased heat. This expansion can cause the electric wire's connections to loosen as the metal components stretch. Additionally, repeated thermal expansion and contraction cycles can contribute to the loosening of the wire.

Why Electric cables between the poles be left loose in summers?
Electric cables between poles are sometimes left loose in summers to accommodate expansion due to heat. When temperatures rise, materials like metals expand, which could cause tight cables to snap or break. Leaving them loose ensures that they have room to expand and contract without risking damage or creating tension that could lead to failure.
What does a electric wire wrapped around a nail cause?
When an electric wire is wrapped around a nail and connected to a power source, it creates an electromagnet. The current flowing through the wire generates a magnetic field, causing the nail to become magnetized. This setup is commonly used in electromagnets and various electrical devices.
What are 3 ways to induce an electric current in a wire?
You can induce an electric current in a wire by moving a magnet near the wire, passing a current through a nearby wire, or changing the magnetic field around the wire.
If an iron bar is inserted into a wire coil what would happen to the iron bar?
The iron bar would become magnetized when inserted into a wire coil carrying an electric current. This is because the electric current induces a magnetic field in the coil, which in turn magnetizes the iron bar.
How does an electric current in a wire deflect with electricity and magnetism?
When an electric current flows through a wire, it creates a magnetic field around the wire. If this wire is placed in the presence of another magnetic field, the two fields can interact, causing the wire to deflect. This phenomenon is known as the magnetic deflection of an electric current.

Could a coiled wire become a bell with electric current?
yes
Do electric current cause coiled wire to become an electric bell?
Yes, when an electric current flows through a coiled wire in an electric bell, it creates a magnetic field around the wire. This magnetic field causes the coil to move back and forth, striking the bell and producing sound.
Inventor of electric wire?
who invented electric wire
Why neutral wire doesn't give electric shock?
The neutral wire doesn't give an electric shock because it is the same potential as ground. That being said if you come in contact with the "hot" wire and the neutral or ground wire, you become the load and will receive a substantial shock.
Why won't an electric window go back up?
It's either a bad Switch, bad/loose wire, or bad window motor
Why current carrying wires become hot?
Current carrying wires become hot due to resistance in the wire. As electric current flows through the wire, resistance causes some of the electrical energy to be converted into heat. This heat energy accumulates over time, causing the wire to become hot.
What is a floating neutral wire?
a loose connection of a neutral wire
What is the third green wire on an electric drill is the wire?
it is the earth wire
How can the loose wire of a starter on a 97 Nissan Maxima be fixed?
If the wire is loose at a connection, find a wrench that will fit it and tighten it.
What does a electric wire wrapped around a nail cause?
When an electric wire is wrapped around a nail and connected to a power source, it creates an electromagnet. The current flowing through the wire generates a magnetic field, causing the nail to become magnetized. This setup is commonly used in electromagnets and various electrical devices.
What is the third (green) wire on a electric drill is the?
It is earth wire
