For the given mixed combination of resistors calculate the total resistance between points A and B.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
This circuit can be solved by consecutively reducing the circuit.
step 1 : 4 and 4 are in series will give us $8\Omega$
step 2: 12 and 12 are in parallel will give us $6\Omega$
Step 3: 6,6 and 6 are in series will give us $18 \Omega$
The correct answer is Option (2) → 18Ω
