Answer 1

When Resistance in series then equivalent resistance must be equal to the sum of all the resiatance.

As in given figure R1,R2,R3,R4 and R5 are in series so equivalent resistance R_{​​​​​​eq.}

R_{​​​​​​eq.}=R_{​​​​1}+R_​​​2+R₃+R₄+R_{​​​​​​5}

_{R1=140 ohm}

_{R2 =160 ohm}

_{R3= 0.1 kilo ohm = 100ohm}

_{R4 = 90 ohm}

_{R5 =125 ohm}

R_{​​​​​eq.} =140+160+100+90+125 =615 ohm
