While checking a diode with a digital multimeter, set to its ‘diode’ symbol, a good diode is expected to show.(1) 0 V in both forward and reverse biasing(2) 0.5 V – 0.7 V in both forward and reverse biasing(3) 0.5 V – 0.7 V in only one direction of polarity(4) 1 in both forward and reverse polarity |

Answer» Correct option: (3) 0.5 V – 0.7 V in only one direction of polarity Explanation: In forward bias, it shows voltage drop across the diode which is small, 0.5–0.7 V. In reverse bias, it shows large, overload, signifying large (∞) resistance. |
