Written Questions: Active Circuits<^< Multiple Choice Quiz: Active Circuits | Course Index | Assignment: Active Circuits >^> The section on the right contains a list of written questions. These can be printed out for your own use. 1. Sketch the circuit diagram of a simple single-stage transistor amplifier. Label your diagram clearly. State the function of each component used and give typical values. 2. Sketch the circuit diagram of a simple power supply using half-wave rectification. Label your diagram clearly. State the function of each component used and give typical values. 3. Sketch the circuit diagram of a simple power supply using full-wave rectification. Label your diagram clearly. State the function of each component used and give typical values. 4. Sketch a typical set of waveforms for a low-voltage DC power supply that uses half-wave rectification. Your waveforms should show: 5. With the aid of a labelled diagram, explain the action of a full-wave bridge rectifier. 6. A transistor switching circuit is to use an NPN silicon transistor having a common-emitter current gain, hFE, of 40, a supply voltage of 10 V and a load resistance of
500 W. <^< Multiple Choice Quiz: Active Circuits | Course index | Assignment: Active Circuits >^> |
