What is the relation of current voltage resistance to one another?

Under normal circumstances, the relationship is given by Ohm's law
voltage = current x resistance.
The ratio of voltage to current is called resistance. This is obtained from the definition of the ohm, and not (as so often stated) from Ohm's Law.
If the ratio of voltage to current is constant for variations in voltage, then the load obeys Ohm's Law and is called a 'linear' or 'ohmic' load.
If the ratio of voltage to current changes for variations in voltage, then the load does NOT obey Ohm's Law, and is called 'non-linear' or 'non-ohmic'. Pure metal conductors ONLY obey Ohm's Law if their temperature is held constant. No semiconductor obeys Ohm's Law.

What are those different power ratings for the same resistance?
The amount of current that will pass through a resistance is dependant upon the voltage applied across the resistance. Voltage devided by resistance equals current. This is Ohm's Law.
What is an example of mass resistance?
An example of mass and resistance is voltage, we know that the following is the formula for calculating voltage: V = IR where R is the resistance and I is the current.
What is the formula for determining potential difference?
This is Ohm's law. It says that voltage (E) equals current (I) times resistance (R). It can be written three ways, and here they are: E = I x R I = E / R R = E / I Voltage and current are directly proportional. What happens to one will happen to the other. What this says is that for a fixed resistance, increasing the voltage will cause an increase in current. Or, said another way, to increase the current through a given resistance, the voltage must be increased. Further, if you double the voltage applied to a given resistance, the current will double. Simple and easy.
What is the formula for electrical resistance?
Resistance(Ohms)= Voltage(volts)/Current (Ampheres) -X
How do i fine an expression for power that involves only current and voltage?
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
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.
Relation between voltage and RPM?
voltage depend on current and resistance r.p.m depend on no of pole
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
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?
What does the size of a current depend upon?
One way to determine current is to measure it, with an ammeter. Another way is to calculate it using Ohm's law: current = voltage / resistance.
How can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
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 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)
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.
Voltage muiltiplied by resistance measures to current?
No. Voltage divided by resistance is equal to current.
