How does a wire's cross section affect resistance?
If two pieces of wire are made of the same material and have the same length but different resistance, then the one with the greater cross section area has the lower resistance.
What is bulk resistivity?
Bulk resistance is the ohmic resistance of the semiconductor material. The natural resistance of a "P" type or "N" type semiconductor material.
What variables do you think might affect the height to which a dropped ball will bounce?
Gravity, air resistance, the material of the ball, and the height from which it was dropped initially.
What is the law of resistance?
The laws of resistance describes the resistance of a specific material. There are a total of four laws of resistance.
What is a material that conducts electric current?
Material with high resistance
Does temperature increase affect resistance?
Yes. The exact effect - whether it increases or decreases - depends on the material.
How does a wire's cross section affect resistance?
If two pieces of wire are made of the same material and have the same length but different resistance, then the one with the greater cross section area has the lower resistance.
Do the resistance depend on temperature and bias voltage?
Yes it depends on temperature and bias voltageAnswerNo. Although temperature may affect resistance indirectly (if actually affects resistivity, rather than resistance), a material will have resistance whether there is a voltage present or not.
Why is electrical resistivity important to a design engineer?
electrical resistance increases current flow decreases.so to know the current flow in the network ,electrical resistance is required.AnswerResistivity is important, because it is one of the three factors that affect the resistance of a material. The other factors are the length and cross-sectional area of the material.
What three factors affect how much electrical resistance an object has?
Any load would do or anything that has resistance. Which is pretty much everything you can hook up to a circuit. For example, lightbulb, buzzer, resistor etc.
How does thickness of a wire affect resistance?
Resistance is inversely proportional to cross-sectional area. so ,if the thickness of the wire increases, the area of cross-section increases and this results in decrease of the resistance. The resistance R = l p / A where R is the resistance, l is the length of the wire, p(rho) is the electrical resistivity of the material and A is the area of cross section. So R the resistance is inversely proportional to A the area of cross-section. If R increases
Three ways which resistance of a wire can be increased?
You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).

What increases resistance in a wire?
Current (measured by an ammeter) and Voltage (measured by a voltmeter) R= V/I Resistance equals voltage divided by current ================================ That's wonderful, but the measurement doesn't "affect" the resistance of the wire. The factors that do "affect" the resistance ... i.e. determine what the resistance will be ... are -- substance of which the wire is composed -- dimensions of the wire: thickness and length.
What factor affects the resistance of a conductor?
This are the factor which affect resistance of a conductor (1). Area of conductor (2). Length of conductor (3) Temperature (4). Type or substance of material used in conducting the electricity.
What is a material that conducts current?
Material with high resistance
