What do you mean by heating effect of current?
The heating effect of current refers to the phenomenon where the flow of electric current through a conductor leads to the production of heat. This occurs due to the resistance offered by the conductor to the flow of electrons. The amount of heat produced is directly proportional to the square of the current and the resistance of the conductor.
What does it mean to have high viscosity?
It means it has a strong resistance to flowing. Liquids like milkshakes, molasses, syrup, and melted chocolate have high viscosities.
What does it mean to have a higher specific heat?
That a given volume of water will store a larger amount of heat energy (per degree temperature rise) than will most other substances.
Does a high or low specific heat mean the substance heats up so fast?
low specific heat is like sand and high specific heat is like water at the beach it may be hot outside the water is still cold but the sand is hot as ever.
What do you mean by Air Resistance?
Air resistance is something that slows down falling objects. A sheet of paper has a lot of air resistance, that is why it falls so slowly.
If it has higher density does it also mean that it has higher resistance?
No. Resistance and density are unrelated properties; for example, salt water is denser than oil, but has a much lower resistance.
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.
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.
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 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.
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 does it mean to have high viscosity?
