The exponent value approaches to unity that is the conduction system in the composite changes from non-ohmic to ohmic with the increase in temperature.
The I-V characteristics of the nanocomposite shows a change in electrical conduction behavior from non-ohmic to ohmic with the increase in temperature from extremely cryogenic to higher one.
Figure 2 shows the graph of these results both with an ohmic fit and with a non-ohmic fit.
A topic "I-V Current voltage characteristics for ohmic and non-ohmic conductors" is added in curriculum 2006 which is a logical change because it helps in drawing graphs for variable I-V to verify the characteristics of ohmic and non-ohmic substances.
1999, The influence of sintering process and atmosphere on the non-ohmic properties of Sn[O.
Furthermore, according to Ohm's law, the resistance, R, is given by the ratio V/i, so we can show how the resistance varies with temperature, which reveals the non-Ohmic behavior of incandescent lamps.
072) values suggest that at lower voltages (region I), the conduction is ohmic, that is, the current changes linearly with voltage, whereas at higher voltages (region II), the conduction is the non-ohmic.
2) conductivity by means of barrier tunneling between particles which have no direct contact, 3) other, non-Ohmic types of conductivity processes, for example, space charge limited conductivity.
By taking into account that the carbon black particles are sources of charge carriers that move freely through the polymer chains, it can be suggested that the conduction process is non-ohmic (I = [kV.
log V indicates that in the low field region the slope is nearly equal to unity showing ohmic behavior, whereas in the high field region the behavior in non-ohmic having slope equal to 2.
However for the PPS/PPY composite, a non-ohmic behavior was observed, and subsequently all measurements were performed in the limits of very low current densities, i.
