Can you use a 12V adapter for 9V?

If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it. Those pedals will work perfectly fine with a 12V adapter.

How do I change my 12V adapter to 9V?

LM7809 is a fixed voltage regulator IC that reduces and regulates the input voltage in electrical circuits. A voltage regulator 12v to 9v converter with IC LM7809 is implemented as shown in the schematic diagram below. It can be used for low current application as well as for the current up to 2 Amperes or more.

Can I use a 12V adapter for 10v?

Can I use 12v/1.5amp adapter in place of 10v/1.2amp adapter? – Quora. No it’s not safe for the most of cases. There are two reasons. Since newer adapter has more terminal voltage therefore device is liable to draw more current and bad thing is that newer adapter is ready to provide more current.

Can I use a 9V adapter for 5V?

The problem with supplying this with 9V is that the current through the circuit would be theoretically near infinate and, as FullFrontalNoodly said, in real life will destroy the circuit very fast. This is because voltage is pressure, like triffid said. A 5V circuit, like a couple LEDs, would leave 4V.

Can a 12V 3A power adapter on 12V 1.5a device?

12V 3A means 3A is maximum current you can withdraw from that power adapter. More than 3A, the voltage will be drop to less than 12 (so your devices wont work as well), or just burn the power adapter. Less than 3A, not a single problem. So yes you can use a 12v 3A power adapter on 12v 1.5A device.

Why is a 9V alkaline battery so weak?

9V batteries are pretty “weak” because the other half of the story is how much current they can supply at that voltage (Power = Voltage * Current). If you want to spin a big motor, the battery voltage will sag because of the battery’s internal resistance.

Can a 12V motor run on a 9v battery?

In principle, it’s probably possible to run a 12V motor on 9V — it’ll just run slower and with much less torque. But if by “a 9V battery” you mean a typical PP3 size battery (i.e, the rectangular ones with a snap connector on top), the answer is almost certainly “no”.
