what is the meaning of ac relay and dc relay
EDIT: a DC relay is simply a coil and core that pulls on an armature. An AC relay usually needs a shaded-pole core (couple of copper loops) to prevent the armature from vibrating at 60 cycles or so. The core, also, is laminated steel like a transformer; so is the armature to help contain the magnetic field. You should not substitute a DC rated relay for an AC , but the reverse should be ok, if voltage and current ratings are the same.

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 is the sign for ac and DC current?
AC means alternating current DC means direct current there is no polarity reversal
What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
Who is the main target for AC DC?
The main target of AC AND DC IS TO GIVE SUUPLY TO CONUMERS WERE AS AC CURRENT IS CHEAPER COMPARING WITH DC
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
What types of magnet either permanent or electromagnetic for AC or DC relay?
What types of magnet either permanent or electromagnetic for AC and DC relay?"how DPDT relay works?
How do you Calculate the contact rating of relay for AC and DC?
On the side of the relay there is a name plate that tells you the current carrying capacity of the contacts. It gives you the ratings at different AC voltages and a DC rating of the contacts at different voltages.
How do you energize a furnace relay?
BY applying a voltage to the relay's coil connections. Could be DC or AC at a specific voltage. If it's DC, watch the polarity. If it's AC, polarity doesn't matter. HOWEVER, VOLTAGE DOES MATTER, so don't go applying 120 VAC to a relay when it needs only 16 VAC, and DON"T APPLY AC to a DC relay. Could burn up quite nicely if you're not careful.
Can you use a 50 amp automotive relay with a 12V dc coil to control 12V ac 500 watt halogen lighting?
No, you cannot use a 50 amp automotive relay with a 12V DC coil to control 12V AC 500 watt halogen lighting. Automotive relays are designed to work with DC power, not AC power. Additionally, the amp rating of the relay refers to its capacity for DC load, not AC load. You should use a relay specifically designed for AC applications with the appropriate voltage and current ratings.
Does ac-dc mean it can run on battery or plug into wall?
AC - Alternating Current, same thing that comes out of a wall socket DC - Direct Current, batteries. <<>> When a device has AC/DC on its name plate, it can work off either of the two voltages. Many portable radios have this function. When the radio is plugged into AC, the voltage is transformed to the working DC voltage and then rectified to a DC voltage. When the radio is on battery operation, the radio operated strictly from the DC voltage supplied by the batteries. The change between voltages from AC to DC or DC to AC is almost instantaneously. This change over is done through an AC powered relay in the radio. When the AC held in relay looses its supply it de energizes and switches over to DC power if the batteries are in the radio. With batteries in the radio try it. Plug into the AC supply, turn on the radio that has batteries installed in it, unplug the AC supply and the radio will not miss a beat.

When the ac is applied to relay what happened?
When current is applied to the windings of the relay, a magnetic field is created, and this will attract the moving part of the relay, which in turn may open or close other electrical contacts. A relay may be operated by either ac or dc according to its design.
Is there any possibilty of ac and DC flows in conductor at a time and get DC and AC with two reference AC and DC?
A typical AC waveform is symmetrical about a zero crossing point. You can bias the AC with DC such that the AC waveform is symmetrical about the DC voltage.

Who is more popular ac DC or poison?
Ac/dc
What county is ac DC is from?
AC/DC are from Sydney, Australia.
