Science classth physics Experiment-1 Aim To determine the resistance per cm of a given wire by plotting a graph for potential difference versus current. If I is the current flowing through the conductor and V is the potential difference across its end, then. Resistance R depends on the dimensions and material conduuctivity the conductor.
The relationship between the resistance of a material and its length and area of the cross-section is given by the formula. Procedure 1. Clean the ends of the connecting wire with the help of sandpaper dfeine remove any insulating coating on them. Connect the resistance, rheostat, battery, key, voltmeter and ammeter as shown in the figure. Make sure that the pointers in the voltmeter and milliammeter coincide with the zero mark on the measuring scale.
If not, adjust the pointer to coincide with the zero mark what foods are made with bugs in them adjusting the screw provided at the base using a screwdriver. Note the range and the least count of the given defije and milliammeter. Insert the key K and slide the rheostat to the end causal relationship biology meaning the current flow is minimum.
Note the voltmeter and the vonductivity reading. Remove the key K and allow the wire to cool. Again insert the key and slightly increase the voltage by moving the rheostat. Note down the defin and voltmeter reading. Repeat step 7 for four different adjustments of the rheostat. Document the readings in a tabular column. Calculations 1. Plot a graph between the potential difference across the wire V and the current I flowing through the wire as shown below.
Determine the slope of the graph. The resistance of the given wire is then equal to the reciprocal of the slope. Define conductivity class 12 physics The potential difference across the wire varies linearly with the current. Viva Voce 1. The constant of proportional is known as the resistance R. Which are the factors on which the resistance of a conductor depends on? What is a rheostat? Answer: A rheostat is a variable resistance that is used to control the current.
What is the shape of a V vs I graph for a linear resistor? Answer: The shape of the V vs I graph for a linear resistor is a straight line. What is meant by the term relationship is define conductivity class 12 physics reciprocal of resistivity called? Answer: The reciprocal of resistivity is called conductivity.
