A sinusoidal voltage Vsin(at) is applied across a series combination of resistance R and inductor L. The amplitude of the current in the circuit is
An AC voltage is applied acrss a series combination of L and R . If the voltage drop across the resistor and inductor are 20 V and 15 V respectiely, then applied peak voltage is
A time varying voltage is applied across A & B such that voltage across capacitor is given by V_(C)=2sin2t . What is maximum potential difference across the reistance?
An amplifier is represented by the circuit shown in Fig. Here r_(i) is the input resistance of the amplifier and the voltage V_(i) is appearing across it. This voltage is amplified by a factor A_(V) and appears across the load as voltage V_(0) An external voltage V_(s) is applied at the input terminals of the amplifier via series resistance R_(S) . What will be the apparent gain A_(V)(=V_(0)//V_(s)) of the ampilifier in terms of A_(V), R_(S) and r_(i).
