You can only reduce amperage in a circut by reducing the number or size of devices plugged in to it. To make it easy, imagine you have a 120watt light bulb. Given your household voltage is normally 120v this would draw 1 amp, (volts X watts = amps). fifteen of these bulbs would draw 15 amps, the size of a commonly used circut breaker. The sixteenth light bulb added to the circut should trip the circut breaker or fuse to protect the wiring from overheating. If you chose to use 60watt bulbs instead you should be able to burn 30 of them before th breaker trips. Likewise if you needed 240watt bulbs, that same circut could only carry 7 of them.

To lower amps in a circuit, you can use a resistor to limit the current flow. By adding a resistor with the appropriate resistance value, you can decrease the amperage in the circuit. Make sure to choose a resistor with the correct power rating to avoid overheating.
the current flowing in the circuit can be reduced by simply adding a shunt resistance
in parallel with the circuit , the shunt resistance must have much lower value than the resistance of the circuit
In order to reduce the electrical current flow there must be more resistance to the flow of electrons. In an AC Circuit the resistance can come from a resistor, capacitor or inductor.
AnswerIn general, you can do this by reducing the load. However, for a load with a poor power-factor (e.g. motor loads), power-factor improvement will reduce the load current. This is achieved by placing capacitors, of appropriate value, across the load.
The answer to this depends on what is your reason for asking.
If there is too much current on the circuit and your breaker is tripping then the only answer is to reduce the load; in other words, unplug things from the circuit until you get to safe current levels.
If you think there should be more current than what you have measured, there is likely a problem with the wiring. It may be an excessively long run of wire causing a significant voltage drop or it may be a loose connection somewhere. If it is a loose connection, it will pose a fire hazard. If it is an excessively long run of wire, you may damage your devices by providing lower than standard voltage levels.
There is only one way to lower amps, is to put more resistance in the circuit but that will mean loss of power
In the electrical trade the only time there is a reference to start and running amps is when dealing with motors. The running amps is always lower than the starting amps. A 78 amp electric furnace will take a 100 amp service for it to operate and be within the electrical code guide lines.
A wire does not produce amps. A wire with a larger cross sectional area allows more amperage to pass through it with less voltage drop due to a lower resistance.
200ma is .200 amps or .2 amps
A basic home freezer typically pulls around 1-2 amps when running. It may draw slightly more when starting up, but it settles to a lower continuous operating amperage.
To convert high voltage (HV) amps to low voltage (LV) amps, you can use the formula: HV amps = LV amps x (LV voltage / HV voltage). By rearranging the formula, you can calculate LV amps by dividing HV amps by the ratio of HV voltage to LV voltage.
