Question

The potential difference across the $3 \,\Omega$ resistor shown in figure is

• A. zero
• B. 3.5 V
• C. 1 V
• D. 7V

Answer 1

Answer: (A)

zero

Answer 2

The two sub circuits are Closed loops They cannot send any current through the $3\,\Omega$ resistor Hence the potential difference across the $3 \,\Omega$ resistor is zero.
