How do you calculate welding machine demand current?
To calculate the current you need to take theWatt rating of your welder and divide this by the voltage youhave setthe machine at- this gives the amperage. So for a 1440 watt welder running at 12v the current would be: 1440 watt/ 12v = 120 Amps
What is the current flow if you apply 12v across a 68 ohm resistor?
0.1764 amps
What will happen if i connect a power supply of higher current rating to lower current load?
The supply won't have to work as hard. It is perfectly acceptable, for example, to use a 1A, 12v supply to supply a 12v, .5A load. The current rating indicates the ability of the supply to dissipate heat caused by the current flowing. If the load current is above the power supply current rating, the power supply will overheat.
What is the charging current and voltage of 12v 180ah battry?
That would also depend on battery chemistry.
What is the current when the voltage is 18 volts and the resistance is 6 ohms?
V=i*r=2*6=12v
How does a 6volt relay circuit works?
The same as a 12V relay circuit, except it only needs 6V instead of 12V.
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?
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.
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
Can you use output 12v 5A for 12v 3.0A?
Yes, you need to match the Voltage, the current (A) need to be the same or higher.
The fuse between 12V car battery and relay for 2x 100w spotlights keeps blowing?
obviously you need a bigger fuse and a bigger relay
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.
Determine the power dissipated if the voltage supplied to a circuit is 12V and the current measured is 3A?
The power dissipated by a circuit with a voltage of 12V and a current of 3A is 36W. Watts is Volts times Amps.
What is output voltage of 12v 5watt solar panel?
The output voltage of 12V 5W solar panel is 12V. The current is 0,41667A. These values are normaly calculated with 1000W/m2 of solar radiation.
Will 1500 watts break 12 volts?
1500W@12V means a current of 125A, that's quite a lot. You have to check what's the max discharge current allowed for your 12V source. There's no general answer.
