`Figure given here shows a metre bridge wire AC which has uniform crosssection. The length of wire AC is 100 cm. X is a standard resistor of 40 and Y isa coil. When Y is immersed in melting ice the null point is at 40 cm from pointA. When the coil Y is heated to 100°C. a resistor of resistance 12 has toconnected in parallel with Y in order to keep the bridge balanced at the samepoint. Temperature coefficient of resistance of the coil is
