Hi, im doing some homework and i cant find anything relating to dynamic resistance. i have many text books but they only refer to diodes.
just wondering if anyone can shed some light on this question
Q8 A 100uF capacitor is connected in parallel with a coil of inductance 100mH. the coil has a small resistance of 10 Ohms. the Circuit is connected across as 100V @ 0 degrees variable frequency power supply.
8.1 Draw a diagram
8.2 the frequency of the supply when the current is at minimum.
8.3 the dynamic resistance of the cct.
8.4 the Q factor of the cct.
i have 8.2 as 50Hz
