# Difference between AC and DC Current in Physics

## Difference between AC and DC Current

Alternating Current:

1. AC is obtained by a resistor that is connected in series with a source of alternating current.

1. Its direction continuously changes.

1. It is obtained by a generator.

1. Its transportation from one point to another point is very easy.

1. It has a frequency about 40 Hz to 60 Hz.

1. No voltage drop takes place in the time of transportation.

1. It is not too dangerous.

1. It is cheaper than DC.

1. It changes very high to low or vice versa.

1. It changes its direction continuously as w and -}r.

Direct Current:

1. DC is obtained by connecting the two ends of a conductor to the terminals of a batter.

1. Its direction remains unchanged.

1. It is obtained by a chemical reaction,

1. Its transportation is very difficult.

1. It has no frequency.

1. Great voltage drop takes place in the time of transportation.

1. It is too dangerous.

1. It is expensive.

1. It cannot change easily.

1. It has no direction.

Note: In general, it is very convenient, because students can get higher education without sacrificing for the sake of his favorite work. But the fact is that not everything is so promising in terms of simultaneous work and study. the fact is that by law a student who works and studies must be released by the employer for the duration of the session. This is evidenced by a certificate sent from the institution. It spells out the precise terms of how the student will learn, that is, at what time he will not be in class. But not every employer will take such responsibility to release his employee. Imagine yourself that a valuable employee will have to be released for more than a month, although this academic leave is not included in the calculation with regular leave. That is, an employee may not be in the workplace for more than two months. Such prospects do not please employers. So, the student learns six years instead of the traditional five, but the university also visits much less often, namely during the installation session and during the examination period.
