With a long-term passage of current I1 = 1.4 A through the wire, the latter was heated to T\ = 55 ° C, and with a current strength I2 = 2.8 A - to T2 = 160 ° C. To what temperature Tx is the wire heated at current I3 = 5.6 me? Wire resistance does not depend on temperature. The ambient temperature is constant. Heat transfer is proportional to the temperature difference between the wire and air.
