The flow of an alternating current switches direction when a generator's terminals change its charge is true regarding current in an external circuit
<u>Explanation:
</u>
Two types of currents, one of them is direct current (DC), constant charging current in one direction. The current in the DC circuits shifts in a constant direction. The amount of electricity can vary, but it always flows from one point to another.
Next is alternating current (AC), the movement of the electric charge periodically changes direction. It is the form most often provided to enterprises and households. The usual form of AC wave is the sine wave. Some applications use different wave-forms, e.g. B. triangular or square waves.
A box is sliding up an incline that makes an angle of 14.0° with respect to the horizontal. the coefficient of kinetic friction between the box and the surface of the incline is 0.180. the initial speed of the box at the bottom of the incline is 2.20 m/s. how far does the box travel along the incline before coming to rest?
Answer:
An AC circuit
Explanation:
In Alternate current, current reverses many times periodically.
