Question

calculate (I) I.e. current

Answer 1

equivalent resistance=5+8+12
=25
we know v=iR
so I=v/R
=6/12
=0.5A

Answer 2

R1=5ohm  R2=8ohm R3=12ohm                         total resistance=25ohm                              voltage in the circuit (V) =6V                     USONG OHM'S LAW ..       V=I/R              VR=I                                                           PUT THE VALUES      6×25=I                    therefore current is 150 ampere
