Q X r E E L s capacitor applied = rs is the series resistance (applies to a coil or a resonant LC circuit) If a capacitor is added to form a series. Introduction Track Circuit is a low powered electrical circuit in which running rails are used as a part. 1 , and phase current I. In AC circuit analysis, if the circuit has sources operating at different frequencies, Superposition theorem can be used to solve the circuit. and that phase power.
