Refer to the circuit diagram given in the figure, which of the following observations are correct?
Observations:
A. Total resistance of circuit is 6 Ω
B. Current in Ammeter is 1 A
C. Potential across AB is 4 Volts
D. Potential across CD is 4 Volts
E. Total resistance of the circuit is 8 Ω
Choose the correct answer from the options given below:
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 .
