What happens to the resistance of a copper wire when it is heated?
The resistance of a copper wire increases when it is heated. This is because heating the wire causes the metal ions to vibrate more, increasing collisions with the electrons and hindering the flow of current, therefore increasing resistance.
Does the wire in the electrical cord of an electric kettle have a higher or lower resistance than the heating element inside the kettle?
The wire in the cord has much lower resistance than the heating element. The heating element is a resistive or resistance heating element. Resistance in the quality of a substance or material that causes it to limit current flow, and it get heated up in the process. The heating element has all but the smallest fraction of the resistance in the circuit, so the heat, that thermal energy that get the water hot, is generated by the resistance of the heating element.
Why does an incandescent light emit light?
An incandescent light emits light due to the heating of its filament wire, which causes the wire to become so hot that it glows and gives off visible light. This process is known as incandescence.
Why a thin wire with heavy weights attached to its ends can cut through an ice block without breaking it?
The pressure exerted by the heavy weights at the ends of the wire causes the wire to melt the ice through friction and localized heating. The thin wire concentrates the force over a small area, allowing it to cut through the ice without breaking it.
Why does heating a metal wire affect its electrical resistance?
Heating a metal wire affects its electrical resistance because as the wire heats up, the atoms within the wire vibrate more vigorously, causing more collisions with the electrons flowing through the wire. This increased collision rate hinders the flow of electrons, leading to a higher resistance in the wire.
What heats the wire of a light bulb?
When electricity passes through the wire of a light bulb, the resistance in the wire causes it to heat up through a process called Joule heating. This heating effect causes the wire to reach such high temperatures that it emits light and produces illumination in the bulb.
Why tungstan light bulb generates so much heat?
The heating of the wire causes light to be emitted.
What causes bubbles to form on spark plug wire insulation?
Wires are Over Heating. Get some heat insulation.
What happens to a nichrome wire when a current flows through it?
When a current flows through a nichrome wire, the wire heats up due to resistance. This increase in temperature causes the wire to glow and emit heat, which is why nichrome wire is often used in heating elements and appliances.
Why is it heating a platinum wire in air is a physical change?
Heating a platinum wire in air is a physical change because it does not change the chemical composition of the platinum wire. The heat causes the platinum wire to expand and may change its physical appearance, but it remains chemically the same.
What happens to the resistance of a copper wire when it is heated?
The resistance of a copper wire increases when it is heated. This is because heating the wire causes the metal ions to vibrate more, increasing collisions with the electrons and hindering the flow of current, therefore increasing resistance.
Does nichrome wire get red hot when current is passed through it?
Yes, nichrome wire gets red hot when current is passed through it due to its high resistance, which causes it to generate heat. This property is used in applications such as heating elements in appliances.

What is the difference between connecting wire and heating element?
The connecting wire will be thicker and made of a low resistance material to allow electricity to flow with minimal losses. The element requires a thinner wire with higher resistivity which causes it to heat when electricity passes through.

What is the proper way to connect the RH thermostat wire to the heating system?
To connect the RH thermostat wire to the heating system, you should match the wire to the corresponding terminal on the heating system. Typically, the RH wire connects to the R terminal on the heating system. Make sure to turn off the power before making any connections to avoid electrical hazards.
