Power = Volt × Current 200=110 × i i =20 / 11 [ E =(65.4/2)] W=(E/96500) × i × t =(65.4/2 × 96500) × (20/11) × 30 × 60 =1.10 g

Q. A $200 W, 110 V$ incandescent lamp is connected in series with an electrolytic cell of negligible resistance containing a solution of $Z n C l_{2}$ . What weight of $Z n$ will be deposited from the solution on passing current for $30$ minutes? (At. wt. of $Z n = 65.4$ )

Power $=$ Volt $\times$ Current
$200 = 110 \times i$
$i = 20/11 [E = \frac{65.4}{2}]$
$W = \frac{E}{96500} \times i \times t$
$= \frac{65.4}{2 \times 96500} \times \frac{20}{11} \times 30 \times 60$
$= 1.10 g$
