Question
The circuit shown in the diagram contains a battery and two wires made of the same material, but with different diameters. Each wire is 10 cm long, has 7 x 1027 mobile electrons per cubic meter, and an electron mobility of 5 x 10-5 (m/s)/(V/m). The diameter of wire 1 is 3 mm, and the diameter of wire 2 is 0.8 mm. Location A is inside wire 1, and location B is inside wire 2. A steady state current flows through the circuit. Show Transcribed Text B wire 1 wire 2 What is average drift speed of electrons at location B, inside wire 2? VB = m/s
