Question

D Derive the expression for in and write formula for Z' for an ac voltage applied to a series
IKRcircuit
Worte the resonance condition for LCR circuit
boy! Explain about transformer and derive the relationship between I, V and N.
3) Explain LC oscillations in detail and draw the analogous diagrams and explain them.
A) A 400 mH coil of negligible resistance is connected to an AC circuit in which an effecuve
current of 6 mA is flowing. Find out the voltage across the coil if the frequency is 1000 Hz.
5) A capacitor of capacitance 102/7 uF is connected across a 220 V, 50 Hz A.C. mains.
Calculate the capacitive reactance, RMS value of current and write down the equations of
vollage and current.​
