Question

Individual Task 3 CO3 1. I-V characteristics is an important characteristic for energy conversion devices. Figure 2 shows a typical 1-V characteristic of a material where the applied voltage is slowly increased la V V Figure 2 (a) Until Va, an ohmic characteristic is observed in Figure 2. However, after Va a peculiar behavior is started to occur. Explain a possible reason for this phenomenon. (b) Propose a characterization technique for measuring the I-V without the peculiar behavior in (a) with justification.

Answer 1

a) 1 va V this is occurs when voltage kturen the the peculiar behavior of material started deve to the electrical breakdown of atomic bond causes creation of lange Number of current carriers. hence break the linear behaviors current is change abruptely wire is very high.

till see that I is directely proportional to V and, any time get the value puting the value of I wer of v and vice-versa.
