The name given by engineers to the ratio of "electrical potential difference" (expressed in volts) to "rate of current flow" (expressed in amperes) is "resistance" (expressed in ohms).

∙ 14y agoIt's known as Ohm's Law
Volts (V) = Current (I) x Resistance (R)
R= V/I
I=V/R

How can you use the calculation of the climate ratio to determine the climate type?
We can calculate the climate ratio to determine the climate type.if the climate ratio is less than 0.4 the climate type would be arid,if the climate ratio is between 0.4 to 0.8 climate ratio would be semirid ,if the climate ratio is between 0.8 to 1.2 climate type would be subhumid andif the climate ratio is greater than 1.2 climate type would be humid.The formula for climate ratio is p/Ep, wherep=precipitationEp=potential evapotranspiration.
How do you prove the Potential density equation?
(rho/potential_density) = (p/reference pressure)^(1/gamma) where gamma is the ratio of specific heats Cp/Cv = 1.40.
What happens to the current in a secondary that has twice as many loops as the primary?
The current in the secondary winding of a transformer is not determined by the current flowing in the primary winding; rather, it is the other way around.The current flowing through the secondary winding of a transformer is determined by the load to which it is connected. The primary current can then be determined from the turns ratio.
What is blow ratio in blow molding?
blow ratio is the ratio of mold diameter to the preform diameter.
What is the ratio of earth to the moon?
The earth/moon radius ratio is about 3.67/1 and the mass ratio is about 80/1.
What is the ratio of electric current and voltage in the closed circuit?
The name given by engineers to the ratio of "electrical potential difference" (expressed in volts) to "rate of current flow" (expressed in amperes) is "resistance" (expressed in ohms).
In an electric circuit resistance is?
Resistance is the opposition to the flow of electric current through a conductor. It is defined as the ratio of the potential difference (volts) between the ends of the conductor to the magnitude of the current (amps) through the conductor.
What is short circuit ratio of an alternator?
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
How do you plot ohms law graph of potential difference versus current?
The current is represented by the horizontal (x) axis, and the potential difference is represented by the vertical (y) axis.If the resulting graph is a straight line, then it confirms that the circuit is obeying Ohm's Law. If the resulting graph is a curve, then the circuit does not obey Ohm's Law.The gradient at any point along of the resulting line represents the resistance of the load for that ratio of voltage to current.
What is short circuit ratio?
Ratio of field current required to produce rated voltage in open circuit to the field current required to produce rated current in short circuit.
The ratio of the potential difference across a metallic conductor to the current in the conductor is known as?
That is the resistance, measured in ohms.
What is the design value of short circuit ration of generator?
short circuit ratio is the ratio of field current to open short circuit voltage n the open circuit current. its value for thermal is less than hydro type.
Define generator short circuit ratio?
Checked Stephen J. Chapman's Electric Machinery Fundamentals page 287. It says: Short Circuit Ratio (SCR) for the synchronous generator is the ratio of the field current required for the rated voltage at OPEN circuit to the field current require for the rated armature current at SHORT circuit.
How do you change the ratio of a current to voltage?
Change the resistance in the circuit
What is relationship between voltage current and resistance?
Ohms Law. I = V / Rwhere V is the potential difference measured across the resistance in units of volts; I is the current through the resistance in units of amperes and R is the resistanceof the conductor in units of ohms.Alternative AnswerThe ratio of voltage (V) to current (I) is called 'resistance', i.e: R = V/I. If this ratio is constant for variations in voltage, then the circuit is said to be 'linear' or 'ohmic', and obeys Ohm's Law. If the ratio changes for variations in voltage, then the circuit is said to be 'non-linear' or 'non-ohmic', and the circuit does not obey Ohm's Law. As most circuits are non-linear, it is clear that Ohm's Law is not a universal law.
What is the Ratio of potential differences across a device to the current that passes through it?
the ratio would be 2:1.
When the current traveling through a resistor is increased what happens to the voltage that travels through the same resistor?
Your question reveals fundamental misunderstandings about the nature of electricity.'Voltage' is simply another word for 'potential difference', and a potential difference appears across opposite ends of the resistor; it doesn't 'travel through' that resistor! Current, on the other hand, DOES 'travel through' the resistor and is caused by the potential difference across the resistor.Resistance is the ratio of potential difference to current. So if the resistance remians unchanged when the current through it doubles, then it has happened because the potential difference has doubled.
