What is resistance welding?
Arc. It's where electrical resistance is used to create the heat for the welding process.
What symbol is often used for electrical resistance?
I have never come across a symbol for an electrical resistance box. As the resistance box is a test instrument and it would not be drawn on any electrical schematic there may not be a symbol designated for it. The last letter of the Greek alphabet is (Ω omega) and it is used for the electrical symbol for resistance.
What is resistance expressed in?
Electrical resistance is measured in Ohms.
What instrument is used to vary electrical resistance in a device?
Virtually all electrical devices (actually, all except for superconducting devices) have resistance. There is one type of electrical device that is found in almost every electronic circuit ever invented. It is used wherever the designer needs a specific amount of resistance in the circuit. I'd hate to spoil your fun by simply telling you its name. Think of all of the different names of electrical devices that your teacher has told you about. (or look in the index of your text book if you're in a hurry) Is there one that comes to mind when you think of RESISTance?
What is the resistance of a unit used to mersure it?
The conventional unit of electrical resistance is the ohm
Is glass a condoctor or an insulator?
Glass is an insulator. It does not conduct electricity well as it has high electrical resistance.
What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
Is glass lens an insulator or conductor?
Glass is an insulator. It does not conduct electricity because it has high electrical resistance.
What is the name of an instrument used to vary electrical resistance?
Rheostat is the name of an instrument used to vary electrical resistance.
Is a glass bulb a conductor or insulator?
A glass bulb is an insulator because it does not easily allow the flow of electricity through it. The glass material used in the bulb has high resistance, preventing the movement of electrical charges.
What is meterial that provides great resistance to the flow of electricity called?
A material that provides great resistance to the flow of electricity is called an insulator. Insulators have high electrical resistance and are commonly used to prevent the flow of electrical current in circuits. Examples of insulating materials include rubber, glass, and plastic.
Is fiber glass a conductor or a insulator?
Fiberglass is an insulator. It does not conduct electricity due to its high resistance to the flow of electrical current. This property makes fiberglass a commonly used material for electrical insulation and applications where electrical conductivity is not required.
What are some ways a material's electrical resistance is used to accomplish a certain job?
A good example of electrical resistance is the heating element on a stove top it is a very poor conductor (high electrical resistance) because it is a poor conductor the electrical energy is converted to heat. Glass is one of the best insulators because its electrical resistance is so high it is a non conductor this lets us use it on high power lines to keep the electricity from coming in contact with the ground.
Does sugar create electrical resistance?
Sugar is not used in electrical circuits.
What is the unit of measurement used by an ohm meter to quantify electrical resistance?
The unit of measurement used by an ohm meter to quantify electrical resistance is ohms ().
Are glass beads a conductor or insulator?
Glass beads are insulators. They do not conduct electricity because they are non-metallic and have a high electrical resistance, which prevents the flow of electrical current through them.
What substances is the worst electrical conductor?
Pure substances such as rubber, glass, and plastic are among the worst electrical conductors because they have high resistance to the flow of electric current. These materials are often used as electrical insulators to prevent or limit the flow of electricity.
