Question

Name some sources of direct current

Answer 1

Direct current:

1. When the electrical current flows consistently in a single direction, then it is called a Direct Current.
2. Hence, this is the current which does not change its direction with time.
3. It is used in any electronic device with a battery for a power source.
4. It is also used to charge batteries.
5. So rechargeable devices like our laptops and cell phones come with an AC (alternating current) adapter that converts alternating current to direct current.

Sources of direct current:

1. Some sources of direct current are cells, DC generators, solar cells, etc.
2. Dry cell, dry cell battery, car battery, DC generator, radio, and television work only with DC.
3. They have a device in them that converts AC supplied to them into DC.

Thus, the common source of direct current (DC) is a battery.
