Question

An electrical current flowing first in one direction & then in the opposite direction is called an:

a. Direct Current (DC)
b. Alternating Current (AC)
c. Static Current (SC)
d. Dynamic Current (DC)

Answer 1

An electrical current that flows first in one direction and then reverses is called Alternating Current (AC).

Step-by-step explanation:

An electrical current that flows first in one direction and then in the opposite direction is called an Alternating Current (AC). Unlike Direct Current (DC), which flows in a single, constant direction, AC periodically reverses its direction at regular intervals. In most homes and businesses, the electricity that powers appliances and devices comes from AC current, typically varying sinusoidally over time.
