Which camera is powered manually?

• A. Hand-Cranked Camera
• B. Electric Camera
• C. Silent Camera
• D. Digital Camera

Answer: (A)

The idea being tested is how a camera is powered: manual versus motorized or battery-driven operation. A hand-cranked camera operates entirely by human effort—an operator turns a crank to move the film and cock the shutter, with no motor or external power involved. This makes it a manual power setup, typical of early cinema when portability and simple mechanics were key.

In contrast, an electric camera uses a motor or external power source to advance the film and run the mechanism, so it isn’t powered manually. A digital camera runs on a battery to power electronic sensors and recording components, again not manual cranking. The label “silent” doesn’t describe power method; it refers to sound recording in the frame, not how the camera is powered, so it doesn’t identify manual operation.
