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 else can I help you with?
What is resistance welding?
Arc. It's where electrical resistance is used to create the heat for the welding process.
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?
How is the ohm's law used in everyday life?
Ohm's Law states that V = IR (voltage = current times resistance). It can be used to find any of those three quantities if the other two are known. It is one of the most important formulae for calculations in electrical circuits - you will use it all the time.
What is the unit to measure the opposition to the flow of electrical current called?
Answer: Inductive reactance is the opposition to the change in current in an electrical circuit and is abbreviated Xl. Answer: The opposition to current flow is called resistance (for DC), or impedance (for AC; often just called resistance); the unit for both is the ohm.
What is the resistance of a unit used to mersure it?
The conventional unit of electrical resistance is the ohm
What is the relationship between resistance and the symbol omega in electrical circuits?
In electrical circuits, resistance is represented by the symbol omega (). Resistance is a measure of how much a material or component opposes the flow of electric current. The symbol omega is used to denote resistance in equations and circuit diagrams.
What are the standard units used to measure electrical resistance, commonly denoted as ohm units?
The standard unit used to measure electrical resistance is the ohm, denoted by the symbol .
What is the significance of the omega symbol in electricity?
The omega symbol in electricity represents electrical resistance, which is the opposition to the flow of electric current. It is used to denote resistance in electrical circuits and is a key factor in determining the behavior of electrical components and systems.
What does symbol ohm mean?
The Om (also Aum) is a Buddhist Hindu word used in chanting - often the translation is the jewel is in the lotus. The last letter of the Greek alphabet is the letter omega (Ω), this letter is also used as a symbol for electrical resistance (Ohm).
What measures electrical resistance?
an ohm meter OR multimeter is used to measure the 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.
What is omega mean in electrical engineering?
in physics it meant Resistance..AnswerThe Greek letter, omega, is used in SI to represent the ohm. The symbol for the quantity, resistance, is a italicised, upper-case, R.
What are some common uses of the mineral petunse in industrial applications?
Petunse, a type of mineral, is commonly used in industrial applications for its properties such as heat resistance, electrical insulation, and abrasion resistance. It is often used in the production of ceramics, refractory materials, and electrical components.
Does sugar create electrical resistance?
Sugar is not used in electrical circuits.
What are devises run by electrical energy represented as resistors in a circuit?
Do not confuse 'resistance' with 'resistor'. 'Resistance' is a quantity, wheras a 'resistor' is a circuit component. In schematic diagrams, the 'rectangular' (European) or 'zig-zag' (US) circuit symbol represents resistance, not a resistor. The circuit symbol, therefore, is used to represent anyresistive device.
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 ().
What does the ohm symbol mean?
The ohm symbol is used to represent resistance of a component or in a circuit
