Factors affect the resistance of a
An investigation into the resistance of increase the resistance by a factor of and see how manipulating these variables affect the resistance of. Objectives: 1 to understand the fact that resistance of the coil increases with the increase of the length 2 to understand the fact that resistance of the coil decreases with the increase of area of cross–section 3 to determine the value of temperature coefficient of resistance (α) of the material of the coil. Resistance is a property of a device or a component like a lamp, a resistor, a thermistor, a diode and so on its value depends on four things 1 what it’s made of metals are good conductors so have lower resistance than an insulator of the same dimensions 2 length – the longer, the greater resistance 3. Three factors affecting air resistance on an object are: a) the speed of the object the greater the speed, the greater the force the units used are m/s b) the drag co-efficient of the object the greater the drag co-efficient, the greater the force. Electrical resistance and conductance there are various other factors that influence resistance and conductance the effect is put to good use. 1 give three factors that affect the amount of air resistance an object experiences, and describe how each factor influences air resistance (will the air resistance go up, or go down if that variable alone were changed.
Factors affecting resistance factors affecting resistance • temperature: in general, for metallic wire, the higher the temperature, the larger its resistance. Physics gcse coursework: factors affecting the resistance of a wire ali hlaiyil introduction: before starting my coursework i have decided to choose 2 factors that will affect the resistance of a wire. 204b resistance 5 define resistance, and explain how it is influenced by blood viscosity, vessel length, and vessel radius 204c the relation. Phys-abm #9: in this experiment, you will collect potential difference and current data for a number of metal rods determine the electrical resistance for each of the readings. Factors affecting the resistance of wire 1883 words | 8 pages aim: to investigate the factors that affect the resistance in a conductor the main factors that affect the resistance in a conductor are: length temperature cross sectional area material magnetism the factor that we are going to change is the cross sectional area. Introduction: resistance is a force, which opposes the flow of an electric current around a circuit resistance is measured in ohms george ohm discovered that a circuit sometimes resists the flow of electricity.
Aim: to investigate the factors that affect the resistance in a conductor the main factors that affect the resistance in a conductor are: the factor that we are going to change is the cross sectional area hypothesis: i think that the higher the cross sectional area, the lower the resistance in the conductor will be. Factors affecting the resistance of a conductor include the material from which it is made, its length, its cross-sectional area, and its temperature.
What factors affect the resistance of a wire (2) nicola tregay the diameter of the wire will have an affect on the resistance of a wire. Investigate one or more factors affecting the resistance of metal wires nichrome since nichrome wire will get hot during the experiment and ohm's law will no longer apply experimenting only on constantan meant that it was not necessary for me to keep the current constant. Temperature: (an increase in temperature will increase the resistance) cross sectional area: (the larger the wire, the less resistance) the length of the wire: (the longer the wire, the more resistance) the material of the wire: (some materials are better conductors than others, and this causes less resistance. The temperature of the material affects the value of the resistance typically the resistance of the material will increase as its temperature will increase typically impact of tiny changes in temperature on the resistance is not thought of as it's negligibly tiny.
But acceleration depends upon two factors: have a direct effect upon the amount of air resistance are the speed of motion » free fall and air resistance. Answer to 2what factors affect the resistance of a conductor select all that apply resistivity geometry temperature none of the.
