A) No change in the energy of the system
B) An increase in the energy of the system
C) Always a decrease in the energy of the system
D) A decrease in the energy of the system unless \[{{Q}_{1}}{{R}_{2}}={{Q}_{2}}{{R}_{1}}\]
Correct Answer: D
Solution :
When \[\frac{{{Q}_{1}}}{{{R}_{1}}}\ne \frac{{{Q}_{2}}}{{{R}_{2}}};\] current will flow in connecting wire so that energy decreases in the form of heat through the connecting wire.You need to login to perform this action.
