A) \[2({{I}_{1}}+{{I}_{2}})\]
B) \[{{I}_{1}}+{{I}_{2}}\]
C) \[{{(\sqrt{{{I}_{1}}}+\sqrt{{{I}_{2}}})}^{2}}\]
D) \[{{(\sqrt{{{I}_{1}}}-\sqrt{{{I}_{2}}})}^{2}}\]
Correct Answer: A
Solution :
Here, \[{{I}_{\max }}={{I}_{1}}+{{I}_{2}}+2\sqrt{{{I}_{1}}{{I}_{2}}}\cos \,{{0}^{o}}\] \[{{I}_{\min }}={{I}_{1}}+{{I}_{2}}+2\sqrt{{{I}_{1}}{{I}_{2}}}\cos \,{{180}^{o}}\] \[\therefore \] \[{{I}_{max}}+{{I}_{\min }}=2({{I}_{1}}+{{I}_{2}})\]You need to login to perform this action.
