Answer:
r_eq = 320 Ω
Explanation:
It is asked to find the equivalent resistance of a series circuit formed by two resistors r₁ and r₂
r_eq = r₁ + r₂
r_eq = 100 + 220
r_eq = 320 Ω
with this value we can find the current that circulates through the circuit
V = r_eq i
i = V / r_eq
i = 6.4 / 320
i = 0.02 A
