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 the three elements of electricity?
The three basic elements of electricity are voltage, current, and resistance. Voltage is the force or pressure that drives the electrical current. Current is the flow of electric charge. Resistance is the opposition to the flow of electric current.
What is the formula for electrical resistance?
Resistance(Ohms)= Voltage(volts)/Current (Ampheres) -X
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 will cause an increase in current flow in a simple series circuit?
An increase in voltage or a decrease in resistance will cause an increase in current flow in a simple series circuit. This is because current is directly proportional to voltage and inversely proportional to resistance according to Ohm's Law.
Does voltage divided by watts equal the current?
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
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.
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)
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
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.
How do you compute for voltage if current and resistance is given?
Voltage = Current * Resistance (Ohm's law)
