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.
Can 9V 1A adapter be used for 12V 1A speakers?
No. If it works at all, it will be underpowered, and possibly damage the speakers. To power 12V speakers, you have to have an adapter with EXACTLY 12V (no more, no less), and at least 1A. You could hook up a 12V 4A adapter if you wanted to, your speakers would just only draw 1A of power. Make sure you use a 12V adapter though!!
Can you use a 12v dc 1a power supply on device that requires 12v dc 3200ma?
No, 3200 ma = 3.2 amps
What is the device called that changes voltage in DC IE 12v 1A to 5v 2A?
If it were just 12V to 5V we would be talking about a simple regulator. Since we are also talking about 1A to 2A, we are talking about some kind of inverter, perhaps a pulse width modulated power converter.
Can you use a 12V 1A sealed lead acid battery charger on a circuit that requires 12V 1A?
The battery is more likely to be marked 12 v 1 Ah, meaning 1 amp-hour, so it can supply 1 amp for an hour, or ¼ amp for 4 hours etc.
Is it ok to use a 5v 1A AC adapter for a device when the original adapter is supposed to be 5V 500mA - will it damage the device?
Yes - what matters is the voltage - it has to be the same. The device will only draws 1A as needed - the adaptor with higher amp,i.e, 2A is fine. As long as the adaptor has amps equal to or greater than those of the device, it will be ok!
Can I use 12V 1A adapter for a 12V 0.16A device?
I wouldn't recommend it ! If the device needs to draw more current than is available - the adapter could overheat, posing a fire risk.
What current will flow if 12v is put across a 12ohms resistor?
V = ir i = v/r i = 12/12 i = 1a
Can you use a 12v 1a adaptor for a 800ma?
Yes, 1 amp is equal to 1000ma and it will be able to operate a 850 ma device.
Is it okay to put a 12v 1000mA unit to 12v 15A power supply?
No B/c ur unit Circuitry design for 1A u can put in 2A MAX 15A may cause burn ur unit
Can you use a 12v dc 1A powerpack on a device that required a 12 dc 700mA?
Yes, the device will only use whatever amps it needs.
Can you use a 12 VDC 2A adaptor on a 12 VDC 1A device?
Yes, there will be no problem with this adapter. The 1 amp device will only be drawing half of what the adapter can produce.
