Home Latest News What Metal is a Good Conductor of Heat What Metal is a Good Conductor of HeatLast updated on 11 November , 2024 In general, metals are shiny, reflecting most of the light that strikes them. They are malleable and ductile (that is, they will bend under pressure and are...
What makes a material a good conductor? A good conductor has free electrons that allow easy transmission of electricity and heat. 12 Why are insulators important in electrical circuits? Insulators prevent unwanted flow of electricity, ensuring safety and directing current flow along intended paths. 10...

Why are metals good conductors, both of heat and electricity? What do you mean by thermal conductivity? What would you expect an electric field to look like inside a hollow conductor? What does excess charge placed on a conductor do?
Why is the electric field inside a conductor zero? How does the electric field become zero in a conductor? Consider a electric space heater. Which method(s) of heat transfer move the heat it produces into the room? Explain. What are non-ohmic conductors?
Since water is a good conductor of electricity, water and water-based extinguishers cannot snuff out a Class C fire. In fact, water can spread the fire and even electrocute the person attempting to put it out. To extinguish a Class C fire, a Class C fire extinguisher should be used. The...
Conductance of a conductor also depends on factors like shape, size, and a specific property known as its conductivity. Conductivity is expressed as and measured as Siemens per meter. The opposite of resistance is conductivity. Since resistance is the opposite of the current flow, conductance is ...
your food is directly immersed in hot oil. The oil completely surrounds every inch of the food, so it gets uniformly crispy. With ordinary baking, your food gets less crispy, because baking cooks by surrounding your food with hot air and air is not as good a conductor of heat as oil. ...
