Questions from David Sang and Graham Jones Solutions for Chapter: Alternating Currents, Exercise 8: Questions with Hints & Solutions
Sketch the voltage patterns of a sinusoidal alternating voltage.
Sketch the voltage patterns the half-wave rectified voltage.
Sketch the voltage patterns for rectified smoothed voltage.
Sketch the voltage patterns for full-wave rectified voltage.
Sketch the voltage patterns for full wave rectified but smoothed.
A student wires a bridge rectifier incorrectly as shown in Figure. Explain what you would expect to observe when an oscilloscope is connected across the load resistor R.
A bridge rectifier circuit that is wired incorrectly.
A bridge rectifier circuit is used to rectify an alternating current through a resistor. A smoothing capacitor is connected across the resistor. Figure shows how the current varies. Use sketches to show the changes you would expect:
A smoothed, rectified current as the resistance R of the resistor is increased.
A bridge rectifier circuit is used to rectify an alternating current through a resistor. A smoothing capacitor is connected across the resistor. Figure shows how the current varies. Use sketches to show the changes you would expect:
A smoothed, rectified current.
(b) if the capacitance C of the capacitor is decreased.
