Answer:
The only information you need to have in order to find the correct power supply for your device is the Voltage / Volts (V) and Amperage / Amps (A).
Voltage has to be an exact match. A 12V DC device needs a 12V DC adapter.
Amperage is the amount of power your device uses. The adapter you order has to be able to supply AT LEAST the amount of Amps your device draws. If your device states it is 12V 3A, a 3A adapter can handle that load, but so can a 4A and 5A. The higher amperage (amp) power supply will not have to work as hard to handle a smaller load, and will run cooler and more stable.
If the Amperage of your device is uneven, such as 3.13A or 4.16A, always round up. 3.13A rounds up to a 3.5A adapter, a 4.16A device will round up to a 4.5A or a 5A.
If you match these two specification (V and A), the power supply will work for your device.
Answer:
0.1 a
Step-by-step explanation:
0.3a + 0.2a + (-0.4a)
= 0.5a - 0.4a
= 0.1a
