ELECTRODYNAMICSII

Transient currents                                                7 hours Max marks 20

Growth and decay of current in LR and CR circuits – measurement of high resistance by
leakage – growth of charge and discharge of a capacitor through LCR circuit – theory of
BG – experiment to determine charge sensitiveness of BG using a standard condenser and
HMS.

4. AC circuits                                                                                 12 hours Max marks 27

AC through L, C, R, LC, CR, LR and LCR – resonance and resonant circuits – repulsion
between coil and conductor – j operators, application to AC circuits – AC bridges –
Anderson and Rayleigh bridge.
