The rate of flow of heat through a copper rod with temperature difference 28^ C is 1400 cal s ⁻¹ . The thermal resistance of copper rod will be

Options

  1. A0.05 ^ Cs cal
  2. B0.02 ^ Cs cal
  3. C5 ^ Cs cal
  4. D2 ^ Cs cal

Correct answer

B. 0.02 ^ Cs cal

Step-by-step solution

Thermal resistance = Temp.difference Thermalcurrent = 28 1400 =0.02 ^ Cs / cal
