Yes.
Yes. mA means milliAmperes. one milli is one/one thousand so 1000mA is 1 Ampere
It depends on what the voltage is: A Watt is a unit of power described as "1 ampere of current pushed by 1 volt of Electro-motive force", therefore 1W = 1A x 1V. 1 kW is a "kilowatt" or 1000 Watts. Using the above formula, and a little algebra, you can find the current required to deliver any amount of power depending on the applied voltage: Current = Power / Voltage; symbolically expressed as I = P / V examples: * 9.5kW x (1000W/kW) / 120v = 79.2 amps * 9.5kW x (1000W/kW) / 240v = 39.6 amps * 9.5kW x (1000W/kW) / 480v = 19.8 amps (Notice how raising the voltage reduces the required current?)
Hexadecimal is a base 16 number system opposed to decimal being 10. This results in counting progressing as follows:-1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, 10, 11, 12.....19, 1A, 1B, 1C, 1D, 1E, 1F, 20...9D, 9E, 9F, A0The reason being, hexadecimal is a 2^n base system and decimal isn't, making it far more applicable to binary storage.

If you know what you're doing, you can probably accomplish that in a 1A circuit.
Unfortunately no, if the device calls for 2000ma you will need a 2A (amp) power supply to adequately power it.
No, it is not safe to use a higher voltage power supply (12V) for a device that requires a lower voltage (7.5V). This can damage the device and potentially cause a safety hazard. It is recommended to use a power supply that matches the required voltage (7.5V) and current (1A) specifications of the device.
Using a 9V 600mA power supply to replace a 9V 1A power supply may not provide enough current to power the device properly. It is important to match the voltage and exceed the current requirements of the device to avoid damage or malfunction.
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.
Yes, you can use a 1A power pack for a 500mA device. The power pack will supply the necessary 500mA the device requires, with some extra capacity. Ensure that the voltage output matches the device's requirement to avoid any potential damage.
The supply won't have to work as hard. It is perfectly acceptable, for example, to use a 1A, 12v supply to supply a 12v, .5A load. The current rating indicates the ability of the supply to dissipate heat caused by the current flowing. If the load current is above the power supply current rating, the power supply will overheat.
Yes, you can use a 500mA (0.5A) supply instead of a 1A supply, but it depends on the requirements of your device. If the device draws more than 500mA, it may not function properly or could be damaged due to insufficient current. Always ensure that the power supply can meet the current demands of your application for safe and effective operation.
12 + 1a - 1a + 1 = 1 + 0 + 1 = 2
No. If it works at all, it will be underpowered, and possibly damage the speakers. To power 12V speakers, you have to have an adapter with EXACTLY 12V (no more, no less), and at least 1A. You could hook up a 12V 4A adapter if you wanted to, your speakers would just only draw 1A of power. Make sure you use a 12V adapter though!!
Yes. (For any pairing of power supply and device, as long as the voltages are a match (in your case: 9v), and the output (in amps or milliamps (A or mA) of the power supply IS EQUAL TO OR GREATER THAN the current required by the device (in your case 1300mA or higher) then you will be fine. Yes it is suitable: The OUTPUT VOLTAGE (5v, 9v, 12v, etc) of a power supply MUST BE EQUIVALENT to the required voltage of the device to which it is to be connected, whereas the output CURRENT (500mA, 1A, 1500mA, 2A... etc) offered by the power supply MUST BE AT LEAST EQUAL TO OR GREATER THAN the current required by the device to which it is to be connected. (in your case, for example, as long as the power supply is rated at 9v, you could use one that has a rating of 1300mA, 1400mA, 1500mA, 1A...and so-on, without any damage to either device)
The 1N4007 diode is commonly used in power supplies due to its ability to handle high reverse voltage (up to 1000V) and moderate forward current (up to 1A). Its robustness makes it suitable for rectification in AC to DC conversion, providing reliable performance and efficient rectification. Additionally, its low forward voltage drop minimizes power loss, enhancing the overall efficiency of the power supply circuit.
