In very high electric field \( E > 10^5 \),
(A) Asymmetric affect disappears
(B) Electrophoretic affect disappears
(C) The ion moves so rapidly that it loses its ionic atmosphere.
(D) The weak electrolyte is completely ionised at all dilutions.
The net current flowing in the given circuit is ___ A.
If the equation \( a(b - c)x^2 + b(c - a)x + c(a - b) = 0 \) has equal roots, where \( a + c = 15 \) and \( b = \frac{36}{5} \), then \( a^2 + c^2 \) is equal to .
