48. a) what is the ratio of potential difference and current known as?
b) The values of potential difference V applied across a resistor and the
corresponding values of current I flowing in the resistor are given below.
P.d V in volts 2.5 5.0 10.0 15.0 20.0 25.0
Current, I in amperes 0.1 0.2 0.4 0.6 0.8 1.0
Plot a graph between vand I and calculate the resistance of the resistor.
