A potential difference of 120 V is applied to a coil at temperature of 12^@C and the current is 6A. What will be the mean temperature of the coil when the curreny has fallen to 3 A, the applied voltage being the same as before ? Given temperature coefficient of resistance coil is .00427^@C^(-1) at 0^@C .
