The term we call "current" was
first introduced in the writings of Ampere, who called it "the intensity
of the flow", "intensite' du courant" in French. Gauss and the Germans
used terminology like "die Stromstaerke" to describe the intensity of "der
elektrische Strom", but adopted the French symbol "I".
So the symbol "I" comes from the French word "intensite'". The word
"current" comes from the Anglicization of the French word "courant".

What is the symbol for voltage in ohm's law?
Voltage = Current x Resistance is often written V = I x R. Ohm's Law is: E = IR E is voltage
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
The current would be about 20 volts.
The unit of electrical resistance is the?
The ohm is used to measure electrical resistance. Plural ohms. With a lil bit of koolaid.The ohm is an international standard unit of measure.Further informationThe basic unit of electrical resistance was given the name "The ohm" in honor of Georg Ohm.Georg Ohm invented the basic electrical law:Resistance (measured in ohms) = voltage (measured in volts) divided by current (measured in amps)which was later given his name: Ohm's Law.Ohm's Law can also be used to find voltage and current when it is expressed as:Volts = amps x resistanceandAmps = volts / resistance.Another answerThe S.I. unit of electrical resistance is the ohm, symbol Ω (omega).1Ω is defined as the resistance of a conductor which allows a 1 ampere of current to flow through it when a potential difference of 1 volt is applied.ohms
What is the voltage drop of a 1k ohm resistor?
It depends on the current going through it. Ohm's law: Voltage equals current times resistance.
What is the unit and abbreviation of current and resistance?
The unit of Current is Ampere. Abbreviation of Current is 'I' and that of Ampere is 'A'. The unit of Resistance is ohm. Abbreviation of Resistance is 'R' and that of ohm is the symbol of 'omega' or the symbol of 'ohm'.
What is the symbol for voltage in ohm's law?
Voltage = Current x Resistance is often written V = I x R. Ohm's Law is: E = IR E is voltage
What does the ohm symbol mean?
The ohm symbol is used to represent resistance of a component or in a circuit
What is the Symbol for mega ohm?
The ohm (symbol: Ω) is the unit ofelectrical resistance in DC circuitselectrical resistance, reactance and impedance in AC circuits.It is named after Georg Ohm.An ohm is the standard measurement of the amount of resistance offered by an object to the flow of electric current. 1 volt of voltage applied across a 1 ohm resistance, will result in 1 ampere current flowing.
What does ohm mean in physics?
In physics, ohm (symbol Ω) is the unit of electrical resistance. It is used to measure how much a material opposes the flow of electric current. One ohm is equal to the resistance that allows one ampere of current to flow when one volt of electric potential is applied across it.
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.
Is M and the ohm symbol together OK for Mega ohm?
Yes, the symbol for megaohm (or megohm) is MΩ.
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 breakdown of the ohm units?
The ohm unit measures electrical resistance. It is represented by the symbol . The breakdown of the ohm unit is as follows: 1 ohm is equal to 1 volt per ampere. This means that if a voltage of 1 volt is applied across a circuit and it produces a current of 1 ampere, then the resistance of the circuit is 1 ohm.
What is AC ohm's low?
ohm's law state that in an electric current it is propotional to current
What is the SI unit of resistance?
The SI unit of resistance is the ohm, represented by the symbol Ω. It is named after the German physicist Georg Simon Ohm, and is used to measure the opposition to the flow of electric current in a circuit.
What are the four basic units of electricity?
Ohm's Law describes the relationship between current ( symbol: I ) and potential difference( symbol: E, V, or U ) under very specific circumstances. It states that 'the current passing through a conductor is proportional to the potential difference across the ends of that conductor, providing various physical conditions, such as temperature, remain constant'.Another way of expressing Ohm's Law is to say that it applies to a conductor (or device) whenever 'the ratio of potential difference to current is constant for variations in potential difference'. The ratio of potential difference to current is known as resistance ( symbol: R ).It should be noted that Ohm's Law is NOT a universal law, and only applies as described in the second paragraph, above. In fact, it applies in very few cases. Hardly any conductors obey Ohm's Law unless their temperatures are held constant (which doesn't normally happen in practice!) and devices such as diodes, etc., do not obey Ohm's Law.So there are three, not four, quantities involved with Ohm's Law: potential difference (which is also known as voltage) expressed in volts (symbol: V), current expressed in amperes (symbol: A), and resistance expressed in ohms (symbol: the Greek upper-case character 'omega').
