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

Answer» 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)` |
