A DC relay is a relatively simple device that uses a single coil, normally wound round an iron core. When a voltage is applied, current flows through the coil and generates a magnetic field. As the magnetic field increases, a spring loaded lever is attracted to the core and moves the switch contacts from an "off" state to an "on" state.
The lever will be held in place as long as the current flows in the coil. When the coil current drops to zero, the magnetic field decays and the lever is released, the spring then pulls it back to it's off position.
What else can I help you with?
Can you use a 50 amp automotive relay with a 12V dc coil to control 12V ac 500 watt halogen lighting?
There are two ways to interpret this question. 1. No you can not use a 12 VDC coil on a 12 VAC source. 2. Check the voltage rating on the automotive relay. If it is approved for AC use then the relay will handle the 42 amps that the halogen lighting will draw. If the relay is not rated for AC use don't use it as the contact surfaces are not rated to handle the current.
How does a 12v to 115v converter work?
A 12v to 115v converter, like an inverter, works by converting direct current (DC) from a 12v source (such as a car battery) to alternating current (AC) at 115v. This is typically achieved through electronic circuitry that switches the DC input to create an AC output, allowing you to power AC devices (such as laptops or small appliances) from a DC power source.
What is the resistance of a 12v lamp in a 12v circuit?
The formula you are looking for is W = I x E.
How many amps in 12v 150w?
Volts * Amps = Watts 12V * A = 150W A = 150W/12V A = 12.5
Can you put 12V 50W light to 12v ac 2A adaptor?
No, you should not connect a 12V 50W light directly to a 12V AC 2A adaptor. The light requires a higher wattage than the adaptor can provide, which can damage both the light and the adaptor. You should use an adaptor that can supply the correct voltage and wattage for the light.
How does a 6volt relay circuit works?
The same as a 12V relay circuit, except it only needs 6V instead of 12V.
How do you test a starter relay in 92 crown vic?
just give it a positive 12v before the starter and after it it will crank after and before if it works
Will a 6V DC 40amp relay fail if 12V 30amp is applied to it?
Probably...The 6V 40A relay figures out as 240Watts...The same relay at 12V 30A figures out as 360Watts.
What could cause the fan to not work on a 1995 neon?
Bad fan motor? supply 12V hot to see if it works - if not bad fan motor Bad relay? Bad sensor?
Where can you buy a 12V relay that activates when the current exceeds 5A?
IN hyderabad near koti
The fuse between 12V car battery and relay for 2x 100w spotlights keeps blowing?
obviously you need a bigger fuse and a bigger relay
Where is the ac relay at on a 1990 Mercedes 300e?
Behind the battery their is a black plastic cover. remove it and the relay is called MAS. Un screw the relay and match the numbers when you get another. Make sure its the relay by checking for 12v at the A/C compressor.

Is a 1999 vauxhall corsa envoy 1.0 12v a 3 clyinder or a 4 cylinder?
12v means 4 valves per cylinder works out at 3 to me
How do I know if I have a bad Fuel pump or fuel relay?
Bypass the relay and if the pump works the relay is bad.
Can a 12v battery be used in a 12v device?
the answer is yes as long as the device works on dc current and not ac current if you tell me what the device is i might be able to help further
Can the fuel pump relay be bad if pump works?
If the pump is running the relay is good.
