Parallel Circuit Advantages Over Series

Steps:

• In parallel wiring, each lamp connects directly to the supply, so breaking one opens only its path, leaving others lit (Student 1 correct).
• Parallel allows independent branches, enabling separate switches for each lamp (Student 2 correct).
• Voltage divides in series but remains equal across parallel branches to the supply voltage (Student 3 correct).
• All statements match parallel circuit properties, confirming option A.

Why A is correct:

• Parallel circuits maintain full supply voltage (V) across each component per Kirchhoff's voltage law, ensuring independent operation.

Why the others are wrong:

• B omits Student 3's valid voltage equality.
• C omits Student 2's independent switching.
• D omits Student 1's fault isolation.

Final answer: A
