Can I use a 12v 18 amp battery and connect to a circuit that asks for 12v Static current 6mA Can I use resistors to lower the amps on the 12v 18amp battery or can I just connect it up?

Just connect the circuit. It will only draw the amps it needs to operate. It is just like connecting a 100 watt light bulb that draws way less than 1 amp, to a 20 amp household circuit.


How many amps does a 5 watt 12 volt bulb draw?

To calculate the amperage, you can use Ohm's Law formula: Amperage (A) = Power (W) / Voltage (V). In this case, for a 5 watt bulb at 12 volts, the amperage drawn would be 0.42 amps (5W / 12V = 0.42A).


How much amperage does a 12v LED draw?

Not enough to worry about. That's like asking how many amps does the memory preset's on your radio draw. It is in the .001-.01 range.


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
