No. At 125 volts, the same 15 amp current results in 10 times as much power. Ohm's Law states that amps x volts = power.

How long will a batery with 125 amp-hour rating run a 60 watt load?
assuming a 12 volt car battery, 60 watts/ 12 volts = 5 amps, 125 amp/hours / 5 = 25 hours of life.
What amp is the yellow fuse?
20 amp on a 12 volt system
Can you use a 5 volt 2 amp power supply on a 12 volt 2 amp device?
No, the voltage of the power supply is not high enough to operate a 12 volt device.
How many watts does my 12 volt 2 amp battery charger draw?
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
How you can pass electricity 20 volt and 25 amp from converting 12 volt 1 amp adopter to 20 volt and 25 amp?
A 1-amp adaptor can not be used for equipment that draws more than 1 amp. It is not clear from the question which part of your system is 12 v and which is 20 v.
Do two 12 volt 100 amp hour batteries give me 200 amp hours at 24 volt?
No. If you connect two 12 volt batteries in series(positive to negative) to make 24 volts, you will have 100 amp hours. If you connect two 12 volt batteries in parallel(pos to pos, neg to neg) you will stay at 12 volts but have 200 amp hours
Will a 5 amp 12 volt power supply power a 12 volt 150 milliamp camera?
YES. The 12 volt 5 amp power supply is an adequate source for 1 12v 150 ma. camera (recommend 1 amp fused "+ "line in)
Can you use car bulb 60watt on 12 volt 7.2 amp battery?
Yes if it is a 12 volt DC bulb.
Can you use 12 volt 2 amp charger to charge 6 volt battery?
No, the output of a 12 volt charger will overcharge and cause the 6 volt battery to boil out its electrolyte
What volt battery charger for a 1982 Toyota Corolla?
12 volt 10 amp charger is what you need.
Can you use a 14 volt 5 amp adapter on a 12 volt 5 amp device?
No you shouldn't use a 14 volt 5 amp adapter on a 12 volt 5 amp device unless you know for sure that the 12 volt device has an internal voltage regulator that will lower the voltage to the correct voltage range the device was designed to use. As long as you always take care to check the output voltage with a voltmeter first, to be sure that the voltage from the adapter is regulated, meaning that it does not rise when a lower current in amps is drawn from it, you may be able to use an adapter that gives the right voltage at a higher amp output rating than the device actually takes. (For example, it may be possible to use a 12 volt 7 amp adapter for a 12 volt 5 amp device.)
Can you use a 12 volt 3 amp power supply on a 12 volt 2 amp device?
Yes you can because the power supply can supply any load at 12 volts with a current between 0 and 3 amps.
Can a 12 volt 0.5 amp ac adapter substituted with a 7.5 volt 1 amp adapter?
Not definitely but it might be possible if the device you are using can accept the lower voltage.
How long does a0.6 amp charger take to charge a 12 volt battery?
A .6 amp charger is a trickle charger. It would take days to charge a dead 12 volt battery with this charger. You need a 10 amp charger which will charge it in a couple of hours.
What power is a 380 amp car battery in volts?
It will be a 12 volt battery.
Can a 12 volt 1 amp battery charger recharge a 12 volt 180 Ah battery?
Yes, but it would take a very very long time. You really need at least a 10 amp charger.
Can you use a 12 volt 1 amp power supply on a 12 volt 2 amp device?
Your power supply can supply 1 A, but your device requires 2 A. So the power supply will be overloaded. So the simple answer is no.
What is the difference between 12 volt 4 amp and 12 volt 5 amp battery?
The capacities of batteries are rated in amp hours. The higher the amp hour rating of a battery the longer the device connected to the battery will operate. Depending on what the connected load draw in amps is, will determine how long the connected device will operate.
Where can you buy an electrical fuse size 12 Amp 125 volts?
It is easy to buy a 12 amp fuse of the right size. The voltage is not needed.
Will a 12 dc volt 8 amp power supply run a 12DC volt 9 amp motor?
Yes but only up to a load torque of 8/9 of the rated torque.
Can you use a 12 volt 2amp supply on a 12 volt 5 amp device?
No. If the device is designed to run on 5 amps, it won't run on 2 amps.
Can you use a 2 amp 12 volt battery charger to charge a 12 volt battery?
A: Yes it can at 2 amp rate. Problems arises when the battery demands more the 2 amps then the power dissipation of the charger can be stressful or damaging
How do you join 12 volt 40 amp wires?
One way to join 12 volt 40 amp wires is with a wire nut cap. The wires are twisted together and then a protective cap is placed over them to ensure they stay joined.
12 kilo volts is equal to how many volts?
12kv is equal to 12000 volt.(12*1000).
How many AMPS will a 10 AMP 12 volt charger charge a 36 volt three battery in series system with?
A 10 amp charge will only output 10 amps and 12 volts. So, if you want to charge thee 12 volt batteries hooked in series you will have to disconnect the positive cable from each battery and charge then individually. You cannot charge three 12 volt batteries hooked in series. That requires a 36 volt charger.
