hi
if anyone can help me solve this problem (T- type low pass filter)it will be appreciated. i have managed to find the current in the capacitor and form there on i don know what to do.
thanks
circuit of a resistive load is fed from a rectifier, via
a filter. The filter is designed to remove unwanted a.c. that might be
present in the output of the rectifier.
To test the performance of the filter, a 50 Hz alternating supply was
connected directly to its input. The resulting
a.c. voltage appearing across the load was then measured.
(a) Sketch a phasor diagram for a circuit
(Hint: begin at the output and work back towards the input.)
(b) Estimate the magnitude of the a.c. input voltage required to give a
voltage of 1 V across RL.
(Hint: show that | XL2 | >> RL and therefore that the entire circuit can
be regarded as reactive.)
both L=1henry
C=100microfarads
RL=10 ohms
