Question
1. A diode characteristic curve is a plot between [a] current and time [b] voltage and time [c] voltage and current [d] forward voltage and reverse voltage 2. The colour of light emitted by a LED depends upon [a] its forward bias [b] its reverse bias [c] the amount of forward current [d] the type of semiconductor material used 3. In a half-wave rectifier, the diode conducts during [a] both halves of the input cycle [b] a portion of the positive half of the input cycle [c] a portion of the negative half of the input cycle [d] one half of the input cycle ...Can you also explain briefly how u chose the answer for each question? Thanks!Explanation / Answer
1. The diode characteristic curve represent the variation ofcurrent through the diode for different voltages (It can be forwardor reverse biased) , hence the answer is [c] 2. The colour of the light emitted by an LED depends on thewavelength, that depends on the energy gap of the semiconductormaterial used. Hence the answer is [d] 3. In a half wave rectifier, the diode conducts during on halfcycle of the input signal. Depending on how the diode is connected,it conducts either in positive half cycle or negative half cycle.Hence the answer is [d]Related Questions
