answered-by-expert Expert Answer
The detailed stepwise solution is as follows:
Step 1) Approach from the closed end. We see that R5, R6 and R7 are in series. Find its equivalent resistance (Say RA).
Step 2) This series combination is in parallel with R4. So find equivalent parallel resistance between R4 and RA. This gives RB.
Step 3) Find equivalent between series combination of RB and R3. This gives RC.
Step 4) RC is now in parallel with R2. So, its equivalent will be RD.
Step 5) Finally R1 is in series with RD. This gives the equivalent resistance of the circuit between A and B.
