1.Find the node voltages using
a)Mesh analysis
b)Node analysis
c)Superposition theorem
2. For the circuit shown in figure below, find the load impedance ZL that absorbs the maximum
average power. Calculate that maximum average power.
3. A series resonance network consisting of a resistor of 30Ω, a capacitor of 2uF and an inductor
of 20mH is connected across a sinusoidal supply voltage which has a constant output of 9 volts
at all frequencies. Calculate, the resonant frequency, the current at resonance, the voltage across
the inductor and capacitor at resonance, the quality factor and the bandwidth of the circuit. Also
sketch the corresponding current waveform for all frequencies.
4. For the figure shown below find the coil current.
ω = 1000rad/sec
5. Find the load current in the circuit shown below.
