A) In Example 25.1, if we doubled the length of the wire whie keeping current fixed, which of the following would change? Check all that apply.
B)
In Example 25.1, if we change the diameter of the wire while keeping current fixed, which of the following quantities must change? Check all that apply.
In Example 25.1, if we change the diameter of the wire while keeping current fixed, which of the following quantities must change? Check all that apply.
drift speed
C)
Which of the following are vectors? Check all that apply.
Which of the following are vectors? Check all that apply.
none of these drift speed carrier concentration (n) current density If there is no electric field inside a conductor, an electron moves randomly from point P1 to point P2 in a time Delta t. If an electric field E is present, the electric force F = qE imposes a small drift (greatly exaggerated here) that takes the electron to point P'2, a distance vd Delta t from P2 in the direction of the force.Explanation / Answer
A)...none of these
B)...current density
carrier concentration (n)
C)...current density
drift velocity
