find the powers consumed by the resistors 2 ohm and 1 ohm
(A) Consider circuit in figure. How much energy is absorbed by electrons from the initial state of no current (Ignore thermal motion) to the state of drift velocity? (b) electrons give up energy at the rate of RI2 per second tot he thermal energy. What time scale would number associate with energy in problem (a)? n= number of electron/volume = 10^29 m^3 length of circuit=10 cm, cross-section A=(1 mm )2
