Find the current supplied by the battery in the circuit shown in figure.

Explanation

All the resistors shown in the figure are connected in parallel between the terminal is,therefore, given by
`(1/R)=(1/12(Omega))+(1/12(Omega))+(1/12(Omega))+(1/12(Omega))`
`or,R=3(Omega).`
The current suppled by the battery is
`i=(V/R)=(3V/3(Omega))=1A.`
