Electrical Power & Heating Effect

In producing chlorine through electrolysis 100 W100\text{ W} power at 125 V125\text{ V} is being consumed. How much chlorine per min is liberated? ECE of chlorine is 0.367×10−6 kg/C0.367 \times 10^{-6}\text{ kg/C}

Show answer and solution

Answer: (a)

  1. I=PV=100125=0.8I = \frac{P}{V} = \frac{100}{125} = 0.8 A.
  2. Charge per minute q=0.8×60=48q = 0.8 \times 60 = 48 C.
  3. m=Zq=0.367×10−6×48≈17.6×10−6m = Zq = 0.367 \times 10^{-6} \times 48 \approx 17.6 \times 10^{-6} kg =17.6= 17.6 mg.
  4. So the answer is (a).
