What is the abbreviation used to represent a unit of electrical current?
AAnswerThe SI unit for electric current is the ampere, whose symbol (not 'abbreviation') is A. The ampere is defined in terms of the resulting force between two current-carrying conductors, due to their magnetic fields.
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 unit of measurement of internal resistance?
unit of internal resistasnce is ohms too. V = I(R+r) V voltage across the circuit I current in the circuit R external resistance r internal resistance unit of internal resistasnce is ohms too. V = I(R+r) V voltage across the circuit I current in the circuit R external resistance r internal resistance
What is an electrical OHM?
A measurement of electrical resistance. It is dimensionally equivalent to Volts / Amperes. (Voltage / Current)AnswerAn ohm is the unit of measurement of resistance. Resistance is not affected by either voltage or current, but by the length, cross-sectional area, and resistivity of the conductor.
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
What is the scientific abbreviation for current?
The scientific abbreviation for current is "I," which stands for electric current.
An ohm is the unit of measurement for?
resistance to an electrical current
Unit of electric resistance?
The unit of electric resistance is the ohm, represented by the symbol Ω. It measures the opposition that a material has to the flow of electric current through it. Smaller resistances allow for a larger current flow, while larger resistances restrict the current flow.
What is the abbreviation used to represent a unit of electrical current?
AAnswerThe SI unit for electric current is the ampere, whose symbol (not 'abbreviation') is A. The ampere is defined in terms of the resulting force between two current-carrying conductors, due to their magnetic fields.
How do you find resistance by a graph?
To find resistance from a graph of voltage vs. current, you can calculate the slope of the graph. Resistance is equal to the slope, so you can divide the voltage by the current to determine the resistance. The unit of resistance is ohms (Ω).
Is ohm the basic unit of resistance?
Yes, ohm is the basic unit of electrical resistance. It is denoted by the symbol Ω and represents the amount of resistance that restricts the flow of electrical current in a circuit.
What unit measures resistance to electrical current?
Ohm (Ω) is the unit that measures resistance to electrical current.
What is The scientific word that means a unit of resistance to the flow of current?
The unit of electrical resistance is the "Ohm", written with the upper-case Greek Omega . . . Ω
What is the ohm unit used to measure?
Ohms measure electrical resistance. The resistance in ohms is the voltage divided by the current.
How much current 2.2 Megohm?
"Ohm" and its multiples is not a unit of current."Ampere" and its multiples is.The current through a 2.2-megohm resistance is(the voltage across the resistance)/(2,200,000) amperes .
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 unit for measuring voltage?
Volts is the unit measurement for voltage Current is amperes or amps for short Resistance is ohms
