Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug electrical appliances into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.

In electrical engineering, a direct current (DC) circuit is an electrical circuit operating with a constant voltage (or current), as opposed to alternating current (AC) circuits. Direct current may flow in a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.

So we know that the root means squared of the sign of Sergio current ice Sabara masses equaling I max the maximum current. And this would be divided by the square root of two. This would be equaling to 1.50 amperes divided by radical too. And we find that the root means squared. Current is equaling 1.606 stamps. That is the end of the solution. Thank you for watching.
