Q
What is the equation for inductance in crossover network?
AA. L = ?2rl / 2πfc
BB. L = ?2rc / 2πfl
CC. L = ?2rl / 20πfc
DD. L = 2πfc / ?2rl
Correct Answer:
A. A. L = ?2rl / 2πfc
Explanation:
A LPF (low pass filter) can be made with the series reactance of L and shunt reactance of C. Thus, the equation for inductance in crossover network is L = √2RL / 2πfC. Where, L = Inductance in Henry RL = Loudspeaker impedance in ohms fC = crossover frequency in Hz
