Questions
In the network shown in figure power dissipated in the 3Ω resister just after the switch S is closed, is(emf= 10V)
detailed solution
Correct option is A
Just after S is closed, the capacitor connect after any resistance to the flow of current.∴ i=10/3 A∴ power dissipated in 3Ω resister = i2R=(103)2×3 W = 1003 W.Talk to our academic expert!
