problem 2: Why RC circuits are generally used as compared to the RL circuits?

problem 3: A step input of 10V when applied to the Low Pass RC circuit generates the output with a Rise time of 200 micro sec. Compute the upper 3dB frequency of the circuit if the circuit employs a capacitor of 0.47 micro F, find out the value of the resistance.

problem 4: A pulse of 5 V amplitude and pulse width of 0.5 msec is applied to the High pass RC circuit comprising of R = 22 K ohms and C = 0.47 microF. Sketch the output waveform and find out the percentage tilt in the output.

problem 5: A pulse of 10V amplitude and pulse width of 1msec is applied to the low pass RC circuit. R = 30 Kohm, C = 0.2 microfarad. Sketch the Output waveform.

problem 6: Make an RC differentiator circuit for pulses of 1ms repletion and 10V amplitude. The trigger pulses are to have 8 V amplitude. The source resistance is 50 ohm and load resistance is 500 ohm.
