Question

which uses direct current?

Explanation:

To determine which device uses direct current (DC), we analyze the power sources:

1. A toaster oven is typically plugged into a household electrical outlet, which supplies alternating current (AC).
2. A flashlight usually operates on batteries (e.g., AA, AAA, or rechargeable batteries), and batteries provide direct current.

So, the flashlight uses direct current.

The flashlight (the lower device in the image) uses direct current.
