Answer:

360/19Ω

18.9Ω

Step-by-step explanation:

FORMULA

1/R(equivallent)= 1/R1+ 1/R2+ 1/R3

R1=40Ω

R2=60Ω

R3=90Ω

1/R(effective)= 1/40+1/60/+1/90

=19/360

therefore,

1/R(eff)=19/360

R(eff) => 360/19

=>18.9Ω

gagandeepsingh8808: plz explain lcm of this question

PrincessManshi: LCM is nothing but lowest common multiple number. so now we have to know the lcm for 40,60,90. for our convenience lets take these number as 4,6,9. now que appears simpler. think of numbers from whch if u multiply u will get the same. 36! 4*9=36, 6*6=36, 9*4=36. now the entre denominator become 36. u solve it now

PrincessManshi: tell me if u understood
