Question 1 An electric current of 6.4 A passing through a resistor has a measured voltage of 9V across the resistor. The resistor is cylindrical with a diameter of 2.5 cm and length of 15 cm. The resistor has a uniform temperature of 115°C and the room air temperature is 23°C. Assuming that heat transfer by radiation is negligible, determine the heat transfer coefficient by convection.
