Convert the current to amperes, then (using Ohm's Law), divide voltage by current.
No, 200mA is not the same as kilohms.Amperes is a unit of current flow. Ohms is a unit of resistance. Other than being related by Ohm's law - Voltage = amperes x ohms - the two units are not the same.
200ma is .200 amps or .2 amps
Yes. Yes, you can replace a transformer with one that has a higher current rating. The load on the transformer should be less than 200mA because presumably that is what the circuit was designed for. Since the current through the transformer should be less than 200mA, the 500mA transformer will not be damaged. The opposite is not true. You should not replace a 200mA rated transformer with a 100mA transformer, for example. If the current exceeds 100mA, the transformer could fry.
Yes. The current rating should be the same or greater than the original. This means the adapter can supply up to 500mA; In your case it only needs to supply 200mA, so it is more than up to the job.
50 mA generally stands for 50 milliamperes. A milliampere is a measure used for small electrical currents.
The charging time for 800mAh batteries depends on the charger’s output current. For example, if you use a charger with a current of 200mA, it would take approximately 4 hours to fully charge the battery (800mAh ÷ 200mA = 4 hours). However, actual charging time can vary based on factors like the charger’s efficiency and the battery's condition. Always refer to the manufacturer's specifications for the best guidance.
There are, 2000/1000 = ,amps in 2000 milliamps. For the math challenged that is 2 amps.
Yes, there is a difference. The 9-volt 2 amp power cord can handle a higher current flow compared to the 9-volt 200mA power cord. This means it can power devices that require a higher current draw without being damaged.
18 Volts.
No. The adaptor will overheat.
Yes, you can use a 6-volt adapter with 200mA in place of a 6-volt adapter with 600mA, but it depends on the device's power requirements. If the device requires more than 200mA to operate, it may not function properly or could potentially damage the adapter. However, if the device draws less than 200mA, the lower-rated adapter may work fine, but it could overheat or fail if the demand exceeds its capacity. Always check the device's specifications for safe operation.
Yes. There's a subtle difference in the meaning of the "--- ma" labels on the two units:-- On the "device" ... the unit that uses power ... the "200ma" is the current it useswhile it's operating.-- On the "adapter" ... the unit that supplies power ... the "800ma" is the maximumcurrent that it's able to supply. Anything less than that is easy.So your adapter is OK to operate your device. In fact, with suitable wiring and a bit ofcooling, it could nominally operate 4 of them at the same time.
