According to the material, which type of current is considered safer?

• A. Alternating current
• B. Direct current
• C. Both are equally safe
• D. Neither is safe

Answer: (B)

Direct current is considered safer because it flows in one direction, giving a single, easier-to-manage shock rather than a continuously reversing wave. This unidirectional flow tends to produce a quick, initial impulse and then a relaxation, making it easier to break contact and disconnect the source. The exposure is typically shorter and more controllable, which reduces the overall risk compared to alternating current, which reverses direction many times per second and can cause repeated nerve and muscle stimulation and complicate release. Of course, any shock can be dangerous, but in the material’s framing, the steady, single-direction nature of direct current is what makes it safer in common safety contexts.
