Questions
Two insulated metallic spheres of 3 F and 5 F capacitances are charged to 300 V and 50 V respectively. The energy loss, when they are connected by a wire, is
detailed solution
Correct option is C
The energy loss when the capacitors are connected by a wire=12C1C2C1+C2V1−V22=123×10−65×10−63×10−6+5×10−6(300−50)2=0.0375JTalk to our academic expert!
