In the circuit shown, the heat produced in 5Ω5Ω resistor is 10cals−110cals^{- 1}. The heat produced per sec in 4Ω4Ω resistor will be

In the circuit shown, the heat produced in 5Ω resistor is 10cals^ - 1 . The heat produced per sec in 4Ω resistor will be

Options

  1. A1cal1cal
  2. B2cal2cal
  3. C3cal3cal
  4. D4cal4cal

Correct answer

B. 2cal2cal

Step-by-step solution

H=I2RtH = I^{2}Rt

∴ \dfrac{H₁}{H₂} = \left(\dfrac{l1}{I2}\right)2 \times\left(\dfrac{R1}{R2}\right)</p><p>or</p><p>or10H2=\dfrac{10}{H₂} =\lleft[1\left(\dfrac{1}{2}\right)] \times\dfrac{5}{4}</p><p>${H}_{2} = 2cal$</p>
