The figure shows a part of a complete circuit. The potential difference \( V_{B}-V_{A} \) when the current \( I \) is 5 A and is decreasing at a rate of \( 10^{3} \mathrm{As}^{-1} \) is given by
(A) \( 15 \mathrm{~V} \)
(B) \( 10 \mathrm{~V} \)
(C) \( -15 \mathrm{~V} \)
P
W
(D) \( 20 \mathrm{~V} \)
