Which of the following is an accurate statement? A There could be two or more reference node in a given network. B The principal node is considered as lower potential with respect to reference node. Any principal node can be used as reference node. The potential between two principal nodes is zero

You work as an engineer in a company and you have been given the assignment of measuring the electrical conductivity and the band gap (Eg) of a new intrinsic semiconductor material at 20 and 100 °C. You cut this material in the form of a rectangular prism with a length of 30 cm, a width of 1 cm and a thickness of 2 cm, and you applied a potential difference of 1 V by placing electrodes on the faces shown in the figure. In this case, you measure a current of 0.8A at 20 °C and 12A at 100 °C. According to this information b) the band gap of this material. 30 ст 2 cm 1 ст
