The field windings of a DC motor are connected to a 220V supply and the motor draw 1.75A at room temperature of 20°С. After the motor has
been working for some hours, the current is measured again and is
found to have dropped to 680mA, although the supply voltage remains
constant at 220V. Calculate the final working temperature of the field
windings, if Ozo is 0.00392/°C.
