The critical current and the current-voltage characteristic of a superconducting film whose width is large compared with the effective penetration depth of the magnetic field is obtained. It is shown that at the critical value of the current the nonvortical superconducting state becomes unstable and that vortex changes are generated at the edges of the films. The current-voltage characteristic of the film shows a voltage jump at a total current much higher than the critical value, and the film resistance ahead of the jump is small compared with the normal resistance. Pinning can lead to the appearance of voltage jumps also at small currents.
