The network shown in the figure is part of a complete circuit. If at a certain instant, the current \( I \) is \( 5 \mathrm{~A} \) and it is decreasing at a rate of \( 10^{3} \mathrm{As}^{-1} \), then \( V_{B}-V_{A} \) equals
(a) \( 20 \mathrm{~V} \)
(b) \( 15 \mathrm{~V} \)
(c) \( 10 \mathrm{~V} \)
(d) \( 5 \mathrm{~V} \)
