1.

Arrange the order of power dissipated in the given circuits, if the same current is passing through all circuits and each resistor is 'r'

Answer»

`P_(2)gtP_(3)gtP_(4)gtP_(1)`
`P_(3)gtP_(2)gtP_(4)gtP_(1)`
`P_(4)gtP_(3)gtP_(2)gtP_(1)`
`P_(1)gtP_(2)gtP_(3)GTP`

Solution :`P_(1)=I^(2)(r/3)...(1)`
`P_(2)=I^(2)xx3r...(2)`
`P_(3)=I^(2)xx(3r)/2.....(3)`
`P_(4)=I^(2)xx(2r)/3....(4)`
comparing the equations
`P_(2)gtP_(3)gtP_(4)gtP_(1)`
