Question

1. in a high pass rl filter, the output is taken

a across the inductor and resistor

b across the resistor and inductor

c across the inductor

d across the resistor

Explanation:

In an RL high - pass filter, the inductor and resistor are in series. The impedance of an inductor \(Z_L = j\omega L\) (where \(\omega\) is the angular frequency and \(L\) is the inductance) increases with frequency (\(Z_L\propto\omega\)), while the impedance of a resistor \(Z_R=R\) (constant). At high frequencies, most of the voltage is across the resistor. At low frequencies, most of the voltage is across the inductor. Since a high - pass filter allows high - frequency signals to pass, the output is taken across the resistor.

Answer:

d. across the resistor
