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

Answer»

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.
