A student used the set up given here to study the dependence of current (I) on the potential difference (V) across a resistor. He kept the contact C in four different positions marked as P,Q,R and S in the figure. On calculating the values of the ratio (V)/(I) for his four readings, he would find that the value of this ratio :

Answer»

for contact at POINT P is `(1)/(4)TH` of that of contact at point S.
for contact at point Q is `(2)/(4)th` of that for contact at point S.
for contact at point R is `(3)/(4)th` of that for contact at point S.
is the same for all the four readings
