Ohm discovered that, for some conductors, the current flowing through the conductor is directly proportional to the potential difference across them. This does not apply to allconductors -in fact, it applies to very few. Ohm's Lawstates that 'the current flowing in a wire is directly proportional to the potential difference across that wire, providing its temperature (as well as other factors) remains constant'.
Ohm's Law makes no mention of resistance. The equation, R= V/I is derived from the definition of the ohm, and not from Ohm's Law, and applies whether Ohm's Law is followed or not. For Ohm's Law to apply, there must be a linear relationship between the ratio of V:I . Those materials that obey this rule are called 'ohmic' or 'linear', while those that do not obey this rule are called 'non-ohmic' or 'non-linear' -most materials are 'non-ohmic'.

What is the relation between internal resistance and load resistance when current is constant in the circute?
The total resistance of a circuit is the sum of the supply's internal resistance and its load resistance, because they are in series with each other. This is true regardless of the magnitude of, or the variation in, the current.
What relationship does Ohm's law express?
Ohm's law gives the relationship between current, voltage, and resistance. The law states that I=V/R, where I is current, V is voltage, and R is resistance. Source: university digital fundamentals
What is the connections between resistance and current?
Ohm's LawVolts = Current x Resistance.
Is a voltmeter a linear scale?
This is because the resistance is measured by applying a fixed voltage to the resistor and measuring the current. Since I = V/R, the current/resistance relation is non-linear.
Using Ohm's Law explain how voltage changes in relation to current assuming that resistance remains constant?
how do you use ohms law express conductance in terms of current and voltage?
Who discovered the relation ship between electic current and resistance?
ohm
Relation between voltage and RPM?
voltage depend on current and resistance r.p.m depend on no of pole

How does voltage change in relation to current assuming that resistance remains constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
What relationship does Ohm's law express?
Ohm's law gives the relationship between current, voltage, and resistance. The law states that I=V/R, where I is current, V is voltage, and R is resistance. Source: university digital fundamentals
Describe the relation between the size of your source and electric current?
The current drawn from a power source is directly proportional to the voltage of thesource, and inversely proportional to the resistance of the circuit between its terminals.There is no relationship between the current and the physical size of the source.
What is the relation between voltage and ampere of any intument?
V=IR where V is the voltage (volts), I is current (amps) and R is resistance (ohms)
What is the connections between resistance and current?
Ohm's LawVolts = Current x Resistance.
What is volt and what is ampier What is the relation between them?
A volt is the unit of measurement for electrical potential difference, while an ampere is the unit of measurement for electrical current. The relationship between them is defined by Ohm's Law, which states that voltage equals current multiplied by resistance (V = I x R). In other words, voltage is proportional to current when resistance is constant.
How much current flows through a lamp with a resistance of 60 Ohms when the voltage across the lamp is 12 V?
The relation between resistance R, Current I and voltage V is: R= V/I Therefore: 60 = 12 / I <=> I = 12 / 60 = 0.2 amp
Who discover current?
The mathematical equation describing the relationship between electric current, voltage, and resistance was discovered by George Ohm in the 1820s. Ohm's Law states that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R), expressed as I = V/R.
Is a voltmeter a linear scale?
This is because the resistance is measured by applying a fixed voltage to the resistor and measuring the current. Since I = V/R, the current/resistance relation is non-linear.
