Question

six registered can connected in our shown in figure find a metre reading when the current is closed​

Answer 1

the resistors CD and CE are in series

so effective resistance across DE will be DE and DCE in parallel which gives (1/2+1/4)^-1

=4/3.now this will be in series with all others so total effective resistance will be 1+4/3+1+1=3+4/3=13/3 ohms

now R=13/3

and V=4V

so I =V/R=4*13/3=52/3=17.33Amperes

hope it helps
