You can use Ohm's Law, which basically defines resistance:R = V/I (voltage divided by current).

What is the cause of resistance and how the resistance and how the resistance of a wire can be determined?

Electrical resistance can be determined by the equation that defines resistance - Ohm's Law. Just divide the voltage across a resistor, by the current passing through it.


How is the total resistance in a series circuit is determined?

The total resistance in a series circuit is determined by adding (summing) the individual resistances of each component in the circuit.


If voltage is high will the resistance be high?

The electric resistance is related to the diameter and extension of the wire submitted to a determined voltage which will determine the electric current flowing into the wire.AnswerVoltage has no effect on resistance. Resistance is determined by the length, cross-sectional area, and resistivity of a material (resistivity is affected by temperature, so temperature indirectly affect resistance).


Which factor does not affect the resistance of a material?

The factor that does not affect the resistance of a material is the color of the material. Resistance is primarily determined by factors such as the material's dimensions, temperature, and composition.


What are the output voltage and current of a transformer determined by?

The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.


How is IMA determined for pulleys?

IMA for pulleys is the resistance force divided by the effort force.


Describe how the resistance of a material is determined?

The resistance of a material is determined by its resistivity, which is a fundamental property of the material. Resistivity is a measure of how strongly a material resists the flow of electric current. It depends on the material's composition and its physical dimensions. The resistance of a material can be calculated using the formula: resistance = resistivity x (length / cross-sectional area).


What determines the extent of resistance to a change of motion?

The extent of resistance to a change of motion is determined by an objects mass. The mass of the object is measured in kilograms.


When a series circuit containing resistance and inductive reactance is connected to a ac supply the current will?

The load current will lag the supply voltage by an angle called a 'phase angle', determined by the values of resistance and inductive reactance. The magnitude of the load current will be determined by the impedance of the circuit, which is the vector sum of the resistance and inductive reactance.


What freature of an object does not affect air resistance?

The internal composition or material of an object does not affect air resistance. Air resistance is mainly determined by an object's size, shape, and speed when moving through air.


What does not affect a material resistance?

Material resistance is not affected by color, texture, or surface finish. It is primarily determined by the material's intrinsic properties such as conductivity, thickness, and temperature.


How can instantaneous current values be determined?

Voltage divided by the resistance of what ever you want to measure the current in.
