What type of electrical current do medical devices typically use?

• A. High voltage alternating current (AC)
• B. Low voltage alternating current (AC) or direct current (DC)
• C. Only high voltage direct current (DC)
• D. None of the above

Answer: (B)

Medical devices typically use low voltage alternating current (AC) or direct current (DC) for several important reasons. Low voltage is essential for patient safety, as it reduces the risk of electric shock and minimizes potential harm during medical procedures. Using alternating current allows devices to be powered efficiently while maintaining a stable power supply. Direct current is often used in devices that require precise control, such as those involved in diagnostics or therapeutic applications. Low voltage DC can safely power sensitive electronics and microprocessors that are integral to the functioning of advanced medical equipment. In summary, medical equipment must operate within a voltage range that ensures safe and effective use, which is why the correct choice highlights low voltage AC and DC as the typical forms of current utilized in medical devices.
