Question
Find the equivalent resistance between points A and B
Advertisements
Solution
As shown in the circuit diagram all the 3Ω resistors re connected in parallel.
`1/R_1=1/3+1/3+1/3`
`R_1=1Omega`
Resistors 4Ω and 6Ω are connected in parallel.
`1/R_2=1/4+1/6=5/12`
`R_2=12/5Omega`
Now R1, R2 and 5Ω are connected in series
`R_(AB)=1+12/5+5`
`R_(AB)=42/5`
`R_(AB)=8.4Omega`
