While performing the experiment of Ohms law, a student has plotted the following graph. The resistance of the conductor will be :
(a) 1000 ï€ï€ï€(b) 10ï€ï€ï€(c) 100 ï€ï€(d) 1As the graph couldn't be drawn,I have given the information drawn from it below:30mA -- 0.3V60mA -- 0.6V90mA-- 0.9V
we know that V= I*R
where V is the potential difference across the resistor
I is the amount of current flowing through the conductor and
R is the resistance of the conductor
R = V/I= 0.3 / (30*10-3) = 10 ohm
2nd and 3 rd reading also give the same resistance
