Why do metallic wires sag in summer?
They expand with heat.
Do wires expand?
Yes as though during the hot days the wires due to the hot heat that make it expand.
Wires with high resistance change electrical energy into what?
Heat.
What causes of heating electrical wires?
when electricity passes tthrouh the wire some amount of energy is taken by the atoms present in the wire.then the atoms viberate and causes wire to heat up.
How is energy produced in a hair dryer?
The heat can travel by the air/oxegyn.Electric can go by the wires/energy.
Why do wires tighten up at night?
At night, there is no sun, thus there is no heat. When there is no heat, solids contract. The wires, being solids contract at night and in the morning, when there is heat, they sag.
Why are wires with high resistance used in light and toasters?
High resistance wires convert the energy used, into heat. That makes the toaster heat up or the light to turn on.
Why are wires with high resistance used in light bulbs and toasters?
High resistance wires convert the energy used, into heat. That makes the toaster heat up or the light to turn on.
What kind and type wire can be used to wire an electric cook stove?
The wires must first be heat resistant. For that the best wires that can be used are wires made up of superconductors.
How do you apply Ohm's law to a toaster?
The wires in a toaster are composed of a metal that heats up when you pass a current through the wires. The voltage, current and resistance for the toaster obey Ohm's Law (Voltage = Current x Resistance). When the wires heat up this heat causes the bread to toast. The toast is not part of the circuit and is not involved in Ohm's Law.
How do you use wires to heat something?
A: Nobody does that. Wires are good conductor never are to be used to heat anything, But there are special wire to do the heating
Why do wires look different during the day and at night?
At night, there is no sun, thus there is no heat. When there is no heat, solids contract. The wires, being solids contract at night and in the morning, when there is heat, they sag.
What type of battery can conduct heat on a wire?
no ONE Wires tHat ConDuCts Heat
Why do you use copper in wires?
we use copper in wires because it is a conductor of both heat and electricity
Why do metallic wires sag in summer?
They expand with heat.
What do the wires inside of a electric jug do?
they hold the heat
Why metal wires sag in summers?
They expand with heat.
