Question

A resistor ′R′ and an element ′Y′ are connected in series to an AC source of voltage. The voltage is found to lead the current in phase by π/4. If ′Y′ is replaced by another element ′X′, the voltage lags behind the current by π/4.
Q8. Identify elements ′X′ and ′Y′. Q. When both ′X′ and ′Y′ are connected in series with ′R′ to the same source, will the power
dissipated in the circuit be maximum or minimum? Q. If the value of R is 20Ω what will be total impedance in series? Q. What will be angle between voltage and current in that situation?
Q. If applied voltage is 200 volt, find peak value of current? Q. Draw the variation for reactance/impedance with angular frequency for Y only.
