# What is the independent variable between resistance and current?

## What is the independent variable between resistance and current?

The independent variable is the thickness of the wire. Which variable is the dependent variable? The dependent variable is the amount of resistance provided by the different wires, as measured by changes in current.

## What is the dependent and independent variable in Ohm’s law?

Independent Variable is the electric current I. Dependent Variable is the voltage V. Control Variables are the material, length, cross section area and temperature of the wire.

What are the dependent and independent variables in a circuit?

Independent variable: length of the wire. Dependent variable: resistance. Control variables: type of metal, diameter of the wire. Conclusion: As the length of the wire increases, the resistance of the wire also increases.

### Is resistance a dependent or independent variable?

Independent Variable is the length of wire. Dependent Variable is the resistance of the wire. Control Variables are the material, the cross section area and the temperature of the wire.

### What is the relationship between resistance and current?

The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.

What is the dependent variable between current and potential difference?

Independent Variable: Potential difference (V) in the circuit. Dependent Variable: The current strength (mA) in the circuit.

## What is the independent variable in Ohm’s law?

Independent variable: The independent variable is the amount of voltage; 5V, 10V, 20V, 35V, and 50V. Dependent variable: The dependent variable is the amount of current that is flowing in a series circuit measured in AMPS or A.

## What are the dependent and independent variables in this experiment?

The independent and dependent variables are the two key variables in a science experiment. The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect.

Is resistance independent of current?

This relationship is also called Ohm’s law. In this form Ohm’s law really defines resistance for certain materials. Ohmic materials have a resistance R that is independent of voltage V and current I. An object that has simple resistance is called a resistor, even if its resistance is small.

### When resistance increases what happens to current?

As the resistance increases, the current decreases, provided all other factors are kept constant. Materials with low resistance, metals for example, are called electrical conductors and allow electricity to flow easily.

### What is the difference between resistance and current?

Current is the rate at which charge is flowing. Resistance is a material’s tendency to resist the flow of charge (current).

What is the relationship between resistance and potential difference?

The current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current.

## How are voltages and resistances dependent on each other?

This example leads me to believe that voltage and resistances and independent variables, and current is dependent on those two variables. But, if we had a circuit with multiple resisters in parallel, then there would be voltage drops between them, making voltage dependent on resistance. I appreciate all help.

## Which is the dependent variable in ohm’s law?

The current is the dependent variable and must be plotted on the y -axis. Using the data you recorded in the second table, draw a graph of voltage vs. current. In this case the independent variable is the current which must be plotted on the x -axis, and the voltage is the dependent variable and must be plotted on the y -axis.

When is the resistance of a conductor Constant?

In other words, at constant temperature, the resistance of the conductor is constant, independent of the voltage applied across it or current passed through it. Ohm’s Law tells us that if a conductor is at a constant temperature, the current flowing through the conductor is directly proportional to the voltage across it.

### Which is a dependent variable in an electric circuit?

In the case of an experiment involving electric circuits, any of the three variables here may serve those roles (yes, even R – think about swapping resistors, or using a variable resistor, and for R as dependent variable, think about heating up a resistor with suitably high current, causing its resistance to change [i.e. behave non-ohmically]).
