An electric current of 5A passing through a resistor has a measured voltage of 6V across the resistor. The resistor is cylindrical with a diameter of 2.5 cm and a length of 15cm . The resistor has a uniform temperature of 90°C and the room air temperature is 20°C. Assuming that heat transfer by radiation is negligible, determine the heat transfer coefficient by convection.
