The forward and reverse current voltage (IV) characteristics of a diode are generally compared on a single characteristic curve. 20 0 obj << This diode either made by silicon or germanium which has atomic number Z=14 or Z=32 respectively. 21 0 obj << ����ҧ This is because the resistance is very low in forward biased condition. The graph showing the forward bias voltage and forward current is known as the forward characteristics, and that showing the reverse bias voltage and reverse current is known as the reverse characteristics. 3. xڅVɒ�6��W�VY�͖�I�$�De'� Q�HE*\��~�z���꧟u�Щot�Xm:�}��E�~�Xm�V�zK�>����x�+~��eh�����j���z�Q6��mX���j�P:���|��Y���s?N�bi��댌�ITi;[�C��"�~� T-|�R��v��[��C��N�Р8&wL�G�D�Pk�t�ֶ١��3�A,��S�/�t,�e�O�~1��?��%?е��*�w�p3Qy�`;�
