Not necessarily. High resistance typically results in more heat dissipation within a material or component due to increased electrical energy being converted to heat. However, other factors like material properties, current flow, and environment can also influence the generation of heat.

What does poor conductor mean?
A poor conductor refers to a material that does not conduct electricity or heat efficiently. This means that it offers high resistance to the flow of electrical current or the transfer of heat energy. Examples of poor conductors include rubber, wood, and plastic.
What is the relationship between voltage and current in electrical systems, specifically, does high voltage necessarily mean high current?
In electrical systems, voltage and current are related by Ohm's Law, which states that voltage equals current multiplied by resistance. Therefore, high voltage does not necessarily mean high current, as the current also depends on the resistance in the circuit.
What do you mean by heating effect of current?
Current flowing through any conductor encounters resistance in that conductor. This resistance produces heat. (Think of tires on a car after driving on the highway. Smooth trip, but a small amount of friction (resistance) is inevitable.
When the thermal conductivty is higher what is it mean?
When thermal conductivity is higher, it means that the material is better at conducting heat. This means that heat transfers more easily through the material, making it a better conductor of heat compared to a material with lower thermal conductivity.
When a material is a good insulator what does it mean?
It depends on whether it's referring to heat or electricity. For heat, it means that it is good at preventing heat transfer from one area to another, for electricity it means it's highly resistant to electrical conductivity.
A thicker resistance wire produces more heat?
I'm not sure what you mean by "thicker resistance" wire? The thicker or more diameter of a wire the less resistance it has. A larger diameter wire would produce less heat. More resistance would produce more heat.
What is a high resistance circuit?
AnswerThe resistance of a material depends on its length, cross-sectional area, and resistivity. This is expressed by the following equation:resistance = [(resistivity x length) / cross-sectional area]So, resistance is directly-proportional to the resistivity and length of the material, and inversely-proportional to its cross-sectional area. So a high resistance can be obtained by increasing the length of the material or by decreasing its cross-sectional area, or by choosing a material with a high resistivity.It's also worth pointing out that resistivity is affected by temperature. For pure metals, the higher the temperature, the higher the resistivity, so the higher the resisistance. For example, a hot (i.e. an operating) tungsten lamp will have a much higher resistance than a cold tungsten lamp.
How the voltage depending resistance works?
There are two ways of looking at this question, depending on what you mean by 'voltage'.The first applies to the supply voltage, which is quite independent of a circuit's load resistance. In other words, changing the load resistance will have no effect on the supply voltage (within limits; for example, and extremely-low resistance might cause the supply voltage to collapse!).The second applies to any voltage drops, which are proportional to the resistance across which they appear. If, for example, you have a high resistance and a low resistance, in series, then the higher voltage drop will appear across the higher resistance.
What does poor conductor mean?
A poor conductor refers to a material that does not conduct electricity or heat efficiently. This means that it offers high resistance to the flow of electrical current or the transfer of heat energy. Examples of poor conductors include rubber, wood, and plastic.
What does heat resistance mean?
The substance that is heat resistant will withstand high temperatures longer than a similar substance that isn't considered heat resistant. compare to Fire resistant and Flame resistant while flame/fire resistance is a function of combustibility, heat resistance is usually associated with the shape the substance normally retains. example? Ice melts at 32F (aka zero C) so if someone could invent an Ice Sculpture that didn't melt until 132F (or even 60F) they could call it heat resistant (and make a fortune to boot)
If the resistance in ohms is higher than the voltage what does that mean?
Voltage is not measured in ohms. It is measured in volts.
If it has higher density does it also mean that it has higher resistance?
Not necessarily. Higher density refers to the amount of mass in a given volume, while resistance is the opposition to the flow of current in a material. They are not directly related, as resistance is dependent on factors like the material's composition, length, and cross-sectional area.
What do you mean by 'cold resistance' and 'hot resistance'?
Metals that make up typical resistors (and many other electrical components for that matter) tend to heat up as current flows through them. "COLD" resistance is the resistance before it is operating and "HOT" resistance is the resistance after some operating time has elapsed.
Why the high resistance earth fault in the appliance increase the risk of electric shock when using appliance in earth situation?
If the earth connection has a high resistance it is not capable of acting as a true earth. For example, the high resistance might mean that the fuse or circuit-breaker will fail to operate when there is a fault.
What is mean of resistive load?
i think it is high value resistance as it is used in Transformers to get the output voltage.
What does UHT mean?
ultra heat treated
What is the relationship between voltage and current in electrical systems, specifically, does high voltage necessarily mean high current?
In electrical systems, voltage and current are related by Ohm's Law, which states that voltage equals current multiplied by resistance. Therefore, high voltage does not necessarily mean high current, as the current also depends on the resistance in the circuit.
