How does a 6volt relay circuit works?

The same as a 12V relay circuit, except it only needs 6V instead of 12V.


Can you use a 12v-0.6a 7.2va adaptor instead of a 12v 1.5a adaptor?

No, you cannot use a 12V 0.6A (7.2W) adapter instead of a 12V 1.5A adapter. The 0.6A adapter provides insufficient current for devices that require 1.5A, potentially leading to underperformance or damage to the device due to inadequate power supply. Always match the voltage and ensure the current rating of the adapter meets or exceeds the device's requirements.


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.


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.


What will happen if use a 12v 400ma instead of 12v 500ma?

i am not sure, BUT according to the answer in this post:Can_you_use_a_9V_600mA_adapter_on_a_9V_400ma_scanneryou need an adaptor of 9v and AT LEAST 500mA (assuming that the appliance draws 500mA)


What is the difference between 12v 7ah and a 12v 7ah 20hr?

12v , 7Ah means its the capicity of Battery , if load current is 1 amp then battery runs for 7 hrs. AH = Ampere* Current. 12v, 7ah 20hrs its shows load current is 7/20 amp.


Why do power windows work with key out of ignition cylinder?

This will be because someone has changed the wiring configuration - The electric window relay should be energised via a switched 12v (either straight from the ignition switch or from ignition relay) to switch a bigger current to power all the windows. In this case someone has removed the relay coil 12v feed from the switched source and connected it to a permanant source (straight from the battery and not via any switches.) -Daz Ellerington.


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


The fuse between 12V car battery and relay for 2x 100w spotlights keeps blowing?

obviously you need a bigger fuse and a bigger relay


How much amps take 12v 50w halogen lamb?

To calculate the current, you can use the formula: current (in amps) = power (in watts) / voltage (in volts). So, for a 50W halogen lamp operating at 12V, the current draw would be approximately 4.17 amps (50W / 12V = 4.17A).


Can you use output 12v 5A for 12v 3.0A?

Yes, you can use a 12V 5A output for a device that requires 12V 3.0A. The device will only draw the current it needs, so having a higher current rating in the power supply is fine. Just make sure the voltage matches and the polarity is correct.


Can you replace 12v 1a adaptor used on device of 12v 700ma?

No, the new adapter will not be able to safely supply enough current.
