Three equal resistace, each of `R` ohm, are connectedd as shown in the figure. A battery of `2V` and of internal resistance `0.1` ohm is connected across the circuit. The value of `R` for which the heat generated in the circuit maximum will be

Options

A. `0.3 Omega`
B. `0.03 Omega`
C. `0.01 Omega`
D. `0.1 Omega`

Explanation

Heat gained in vaporization = Heat released in fusion
`m_(1)L_(v)=(m-m_(1))L_(f)`
`(m_(1))/(m-m_(1))=(L_(f))/(L_(v))=(1)/(7)`
`7m_(1)=m-m_(1)`
`8m_(1)=m`
`(m_(1))/(m)=(1)/(8)=(x)/(y)`
