The resistance of a parallel circuit con-
sisting of two branches is 12 ohms. If
the resistance of one branch is 18 ohms,
what is the resistance of the other ?

Answer:
36 ohms
Step-by-step explanation:
When resistances are connected in parallel then,
(1/R eff)=(1/R1) + (1/R2) [R eff is the effective resistance of the total circuit]
=>(1/12)=(1/18)+(1/R2)
=>{(1/12)-(1/18)}=1/R2
=>{(3/36)-(2/36)}=1/R2 [By taking LCM]
=>1/36=1/R2
=>R2=36 ohms.
