Q3.31Multiple choice
This question refers to a figure in the original PDF.
- (a)Consider circuit in Fig 3.10. How much energy is absorbed R = 6 by electrons from the initial state of no current (ignore thermal I motion) to the state of drift velocity? I
- (b)Electrons give up energy at the rate of RI2 per second to the thermal energy. What time scale would one associate with energy in problem (a)? n = no of electron/volume = 1029/m3, V = 6V length of circuit = 10 cm, cross-section = A = (1mm)2 Fig 3.10
