yes, as long as the voltage is the same, the device will only take what it needs as far as amperage.
No, a 5V 500mA power supply cannot run a 5V 1.8A device. The device requires 1.8A of current to operate properly, while the power supply can only provide 0.5A. Attempting to use the lower-rated power supply could result in insufficient power, causing the device to malfunction or not turn on at all.
No, the 1A power supply does not provide enough current (3200mA required) for the device to operate properly. You need a power supply that can deliver at least 3200mA to meet the device's power requirements. Using an underpowered supply may result in the device not functioning correctly or potential damage.
No you can not. The power supply output of 5 volts is under sized. There is no way that a 45 volt device would operate from it. You will need to find a power supply of 45 volts.
Yes, 1000 ma equates to 1 amp. The 4 amp power supply will have more than enough capacity to operate any device drawing 1 amp.Just make sure that the voltages match. AC voltage of the power supply to AC voltage on the device. You can not cross voltages using a DC power supply to operate an AC device, or the other way around, an AC power supply to operate a DC powered device, even though the voltage values are the same.
Yes, you can use a 300mA power supply in place of a 400mA supply, but it may not provide enough current for the device to operate properly. If the device requires 400mA and only receives 300mA, it may underperform, malfunction, or even be damaged due to insufficient power. It's important to ensure that the power supply meets or exceeds the current requirements of the device for safe and effective operation.
A power supply that produces 1.8 amps is the same as saying 1800 mA. What has to be taken into account here is if the voltages are the same. If the device that uses 700 mA has a specific voltage to operate on can the power supply provide the same voltage. Another factor to look at is , both the device and the power supply have to match their AC or DC requirements. One can not be AC and the other DC or vice versa.
Yes you can but for devices use 12 v and 500 ma( 0.5 a) <<>> No, the output of the 500 mA power supply will be too small for a device that requires 700 mA to operate. It can be done the other way around though, a 700 mA power supply will operate a device that only requires 500 mA with 200 mA to spare.
power supply is a device that supplies electric power to electrical load
R = resistor L= Inductor C= Capacitorphi P= Power supply and Load i.e a device to operate
The simple answer is, No. But I'll give you the long answer, too. The power rating of most devices is the maximum power used under unusual circumstances. Most devices, unless it's something like a light bulb which is either on or off, don't use their max power 99% of the time. If you protect the circuit with a 1.0 amp fuse you protect your power supply and device and you can safely see if it works.
