In The Circuit Shown In The Figure Below The Two Thick Wires And The Thin Wire Are Made Of Nichrome The Emf Of The Bat 1 (73.81 KiB) Viewed 109 times

In the circuit shown in the figure below, the two thick wires and the thin wire are made of Nichrome. The emf of the battery is 1.5 V. In Nichrome there are n=9×1028 mobile electrons per m3, and the mobility of mobile electrons is u=7×10−5( m/s)/(N/C). Each thick wire has length L1​=27 cm=0.27 m and cross-sectional area A1​=6×10−8 m2. The thin wire has length L2​=2 cm=0.02 m and cross-sectional area A2​=1.9×10−8 m2. (The total length of the three wires is 56 cm.) In the steady state, calculate the number of electrons entering the thin wire every second. Do not make any approximations, and do not use Ohm's law or series-resistance equations. electrons/s Attempts: 1 of 10 used
