In the circuit of figure 1, the battery has an e.m.f. of
3.00 V and an internal resistance r. R is a variable
resistor. The resistance of the meter Mi is
negligible and the meter M2 has an infinite
resistance.

temperature
B resistance increases with an increase in
temperature
C resistivity increases with decrease in
temperature
D resistance decreases with increase in
temperature
