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