Can you have more amps than volts?
You can’t have a lot of amps without a lot of volts. Given your body is a constant resistance, it really is a combination of both. Higher voltage means higher amperage, and thus higher voltage has more potential to kill. It takes only 100mA to stop your heart.
How many amps is the power supply rated for at 12 volts?
Based on the sticker on this power supply 12v maxes out at 62 amps. Perfect. Unfortunately the 12 volt wires are 18 gauge, which after some googling seem to safely max out at around 7-10 amps. Even wiring the two together could only support around 20.
Which is worse amps or volts?
Voltage and amperage are two measures of electrical current or flow of electrons. An electrical current at 1,000 volts is no more deadly than a current at 100 volts, but tiny changes in amperage can mean the difference between life and death when a person receives an electrical shock.
How do I bring my amp down?
In order to lower the amperage of an electrical circuit, you must either lower the circuit’s voltage or increase its resistance. Lowering amperage is done by applying Ohm’s law, given by the formula I = V/R, where I is the circuit’s total current in amperes, V is the voltage and R is the resistance.
Can a 12V power supply supply 10 amps?
A power supply has a voltage and current rating (amongst other ratings). The power supply will normally supply the rated voltage up to the rated current. Just because a 12v power supply can supply 10 amps, doesn’t mean that the power supply will force 10 amps through the circuit.
Is it okay to use a power supply that provides slightly more voltage?
This doesn’t mean your device will consume 3.42 A when its powered with this adapter; it is only an indication of the maximum current that can be drawn through the adapter by any device that it is connected to, above which the adapter gets damaged. Any device will only draw as much current as it needs, so long as its power source can supply it.
What’s the maximum current a power supply can draw?
All supplies have some maximum current they can provide and still stick to the remaining specs. For a “12 volt 1 amp” supply, that means all is fine as long as you don’t try to draw more than the rated 1 A. There are various things a supply can do if you try to exceed the 1 A rating.
What should the voltage be for a 12V LED strip?
After this minimum threshold voltage, power draw increases by approximately 1.0 watts per foot every 0.75 volt and 1.5 volt increase for 12V and 24V LED strips, respectively. A common voltage level for laptop power supplies is 19.5V DC, so you might find these results useful if you’re in a pinch, and that is the only power supply you have on hand.
