Final answer:
Rapid, interrupted electric current that changes directions periodically is known as alternating current, while vehicles use direct current. so, option d is the correct answer.
Step-by-step explanation:
Rapid, interrupted electric current that flows in one direction and then in the opposite direction is called alternating current. When referring to the type of current used in cars, the correct answer would be direct current(c). This is because the electrical systems in vehicles are designed to run on a steady, unidirectional flow of electricity. As a contrast, alternating current is characterized by its ability to change direction at regular intervals. Common household outlets provide alternating current for domestic appliances.
The rapid, interrupted electric current that flows in one direction then in the opposite direction is called alternating current (AC).
Unlike direct current (DC), which flows in only one direction, alternating current changes its direction of flow at regular time intervals. AC is commonly used in homes and businesses and is generated by sources such as hydroelectric dams.
Examples of AC include the current that comes from a normal wall socket and the power used in cars.
