Question

Find equivalent resistance between A & B in the circuit is


  1. 8.5 Ω

  2. 16.5 Ω

  3. 49 Ω

  4. 18 Ω


Solution

The correct option is B

16.5 Ω


Since 12Ω & 18Ω are in series & we know,
For series connection, Req=R1 +R2 +R3 +........ +Rn 
We can substitute (12Ω + 18Ω) as 30Ω.
Now, 30Ω & 10Ω are in parallel & we know,
For parallel 1Req= 1R1 +1R2 +1R3+........ +1Rn
 1R= 130 +110= (1+330)1R= 430R= 304= 7.5
Now 9Ω & 7.5Ω are in series & we know,
for series Req=R1 +R2 +R3 +........ +Rn
Req= 9+7.5= 16.5
