In following circuit potential at point 'A' is zero then determine
(a) Potential at each point
(b) Potential difference across each resistance
( c) Identify the batteries which act as a source
(d) Current in each battery
( e) Which resistance counsumed maximu power
(f) Which battery consume or gives maximum power.

Answer

(a)`V_(A)=V_(B)=V_(C)=V_(D)=0V,`
`V_(E)=V_(F)=V_(G)=V_(H)=10V,`
`V_(I)=V_(J)=V_(K)=15 V`
(b) `V_(I)=15V, V_(2)=5V, V_(3)=15V`
( c) each act as a source
(d) `17.5 A(uarr), 15A(darr)2.5 A(uarr), 5A(darr)" form left to right in given circuit"`
( e) `1 Omega` resistance
(f) left most battery.
