Silver and copper voltmeters are connected in parallel with a battery of emf `12V`. In `30` minutes, `1g` of silver and `1.8g` of copper are liberated. The power supplied by the battery is
`(Z_(Cu) = 6.6xx10^(-4) g//C and Z_(Ag) = 11.2xx10^(-4)g//C`)

Options

A. 24.13J/sec
B. 2.413J/sec
C. 0.2413J/sec
D. 2413J/sec

Explanation

`i_("silver")=(1)/(11.2xx10^(-4)xx1 800)` amp
`=0.49approx0.5` amp
` i_("copper")=(1.8)/(6.6xx10^(-4)xx1800)` amp
total current +(approx)=2amp
power =vi=24(approx)
