DC Current is used in the various devices we have. Assuming your talking about transmission and distribution, you can step-up AC voltage to very high values with Transformers. The size of the conductor carrying that high voltage can be very small. At the destination, the high voltage is stepped back down with another transformer. You could not do any of this with DC
What else can I help you with?
Are diodes only used in a dc circuit?
There are lots of diodes - a "diode" is simply a device that has two electrical connections.If you refer specifically to the rectifying diode, it is used to convert AC current to DC current - so, it is used in a circuit that has BOTH AC and DC.
Why DC is used in battery's?
dc in battery stands for direct current .ac is alternating current.
Does the galvanometer measures AC and DC current?
It is used to detect very small DC currents only. For AC signals Detectors are used.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
What IS AC DC?
AnswerThere is a hard rock band called AC/DC .In electrical jargon, AC is short for alternating current and DC is short for Direct current.
What is the sign for ac and DC current?
AC means alternating current DC means direct current there is no polarity reversal
Will an AC electric motor run on DC?
No ... AC means Alternating Current - DC means Direct Current. DC is used mostly for electronics and for voltages within our vehicles. AC is used for motors and for our household appliances and lamps.
Can rheostat run on AC current and DC current?
Yes, a rheostat can be used with both AC and DC currents. The rheostat's variable resistor can be adjusted to control the current flowing through a circuit, regardless of whether it is AC or DC.
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
What are the key differences between alternating current (AC) and direct current (DC)?
Alternating current (AC) and direct current (DC) differ in the direction of flow of electric charge. AC changes direction periodically, while DC flows in one direction continuously. AC is used for long-distance power transmission, while DC is used for electronic devices and batteries.
Which type of current flowing in the house ac or dc?
AC current is used nearly everywhere. You will only find DC in special cases, such as solar powered houses, but the utility connection used for backup is still AC.
Can only direct current be used for charging batterys?
No, alternating current (AC) can also be used to charge batteries using a charger that converts AC to DC. The charger will convert the AC power from the outlet to DC power that is suitable for charging the battery.
