Which type of electric current is typically supplied to our homes?

• A. Direct current ($DC$)
• B. Static current
• C. Alternating current ($AC$)
• D. Pulsed current

Answer: (C)

Verified step by step guidance

1. Understand the difference between types of electric current: Direct Current (DC) flows in one constant direction, Alternating Current (AC) periodically reverses direction, Static current refers to stationary electric charges, and Pulsed current consists of bursts of current separated by intervals.
2. Recall that the electric power supplied to homes is generated and transmitted over long distances, which is more efficient using Alternating Current due to easier voltage transformation and reduced energy loss.
3. Recognize that Alternating Current (AC) allows the use of transformers to step voltage levels up or down, which is essential for safe and efficient power distribution in residential areas.
4. Note that Direct Current (DC) is commonly used in batteries and electronic devices but is not typically used for general household power supply.
5. Conclude that the type of electric current typically supplied to homes is Alternating Current (AC) because of its advantages in generation, transmission, and distribution.
