jodi made a list about electric current to her study for a test.
1) movement of electrons is continuous in a current.
2) electrons move from areas of low to high electric potential.
3) voltage causes current to flow.
4) rate at which current flows is measured in amperes
which best describes jodi’s error?
the movement of electrons is not always continuous.
electrons move from areas of high to low electric potential.
resistance causes current to flow.
the rate at which current flows is measured in ohms.

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
