6 FAQs about [How many milliamps does an outdoor power supply require]

Can a 12V power supply supply 10 amps?

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. It is, generally, not okay to supply a component with more current than its rated for.

How much a power supply can flow?

It will only allow up to a maximum of 5A to flow and how much actually flows depends on the power supply voltage and the effective total resistance of the circuit connected to it. A simple example: You can have a power supply rated for 5V at 1 billion Amps. Now say you attach a resistor to this supply, lets say 5 Ohms.

What happens if a power supply exceeds the current required?

Note: the current provided by the power supply will typically exceed the amount of current required by the device, the device in turn only ‘uses’ the amount of current necessary leaving additional current available for other devices in the chain.

How many ft can a strip light hook up to a power supply?

You can connect more than 42 feet of LED strip lights to a single power supply by installing the runs in parallel. Make sure to check the product specifications or markings on the strip to ensure proper voltage input.

What makes a good power supply?

If it’s not made specifically for your particular computer, getting the right power supply is important and involves matching voltage, amperage, and polarity. Each has different constraints. The output voltage must match. The output amperage must match or be greater than that required by the device being charged or powered.

What voltage do I need for a 55W power supply?
