Solution
Explanation:
In (b), (c) and (d), R1 and R2 are in parallel across the cell, with R₃ in series or parallel as shown. In (a), all three resistors are in a single series path, so it differs from the others. Series gives total resistance R1 + R2 + R3, which is different in structure from the others.
