Find the expression for resistors connected in series.
Find the equivalent resistance between points A and B
Name a substance of which the resistance remains almost unchanged by the increase in temperature.
Answer the following question.
While studying the dependence of potential difference ( V) across a resistor on the current (I) passing through it, in order to determine the resistance of the resistor, a student took 5 readings for different values of current and plotted a graph between V and t. He got a straight line graph passing through the origin. What does the straight-line signify? Write the method of determining the resistance of the resister using this graph.
State expression for Resistance connected in parallel.
What is the equivalent resistance between the points X and Y for the given network?
A metal wire of resistance 6 Ω is stretched so that its length is increased to twice its original length. Calculate its new resistance.
Two wires of same material and same lengths have radii in the ratio of 2 : 3, Compare their resistances.
